I thought I would give you an excerpt of my upcoming book in regards to vaccines during pregnancy seeing as this is a very hot topic right now :)
VACCINES DURING PREGNANCY?
When your midwife or GP is recommending the Flu Vaccine or the Whooping cough vaccine, do they tell you these facts?
1 - Not a single licensed vaccine has ever been tested on a pregnant woman?
2 - The manufacturers themselves state that they do not recommend vaccines during pregnancy as the damage to the baby is unknown?
3 - The whooping cough vaccine, is not just a single vaccine. It is called Boostrix IPV and it is a 3 in one booster vaccine for Pertussis, Diptheria and Tetanus ?
4 - The booster vaccine contains - formaldehyde, aluminium hydroxide, sodium chloride, polysorbate 80? 
5 - That there is a 4,250% increase in fetal deaths after the flu vaccine?
There are many studies to prove how dangerous it is to receive a vaccine during pregnancy. There is currently no data to suggest that catching the wild strain influenza whilst pregnant can cause a miscarriage or fetal death, but many studies proving that receiving the flu vaccine during pregnancy can.,,,,
A study comparison on the two-vaccine 2009/10 influenza season conducted by Dr Neil Z Miller and Paul G King, PhD concluded that thimerosal based vaccines were attributing to the cause of still births and miscarriage in pregnant women .
“Thimerosal has been found to be toxic at very low levels. For example, Parran et al. examined the effects of Thimerosal on cell death in a human neuroblastoma cell line. Following 48 h of a single dose of 4.35 nanomolar Thimerosal (or about 0.87 mcg/kg of mercury) over 50% of cells were dead.
Thus, it is biologically plausible that during the two-vaccine 2009/2010 influenza season, when pregnant women were administered two Thimerosal-containing influenza vaccines each delivering 50 mcg of Thimerosal (or 25 mcg of mercury per dose), the fetus' mercury dose exceeded the EPAs reference dose (0.1 mcg of mercury/kg/day). This overexposure could be a significant contributing factor to some of the reported SABs and SBs. Moreover, the mercury in injected Thimerosal-containing vaccine doses has been found to preferentially bioaccumulate in the fetal tissues. This study demonstrates that depending upon the gestational age, the safety level of mercury (as specified by the EPA’s reference dose) may be exceeded by several thousand fold for an early developing fetus during the first trimester to a factor of just over 1 at full-term – even for a single reduced Thimerosal vaccine dose presuming only 50% of the mercury (0.5 mcg) bioaccumulates in the fetus.”
Miller goes on to conclude - “Thus, a synergistic fetal toxicity likely resulted from the administration of both the pandemic (A-H1N1) and seasonal influenza vaccines during the 2009/2010 season.”
According to the NHS, these are the things you must stay away from in pregnancy -
High mercury fish
Liver and liver products
But apparently, these things are fine -
(all contained in the Boostrix pregnancy vaccine) 
The human race is about 300 generations old. At least 290 of those generations had no allopathic pharmaceutical involvement whatsoever, and approximately 298 of those generations, had no vaccines. Yet, the United States has the highest maternal and infant mortality rate in all of the developed countries, the UK is 4th. The lowest of those is Norway, where vaccines are not forcefully pushed upon an expectant parent.
FOLIC ACID OR FOLATE ?
Folic Acid is pushed a lot during pregnancies. The NHS states - “Folic acid is the man-made version of the vitamin folate (also known as vitamin B9). Folate helps the body make healthy red blood cells and is found in certain foods.”  Unfortunately, it is just another way for the Pharmaceutical industry to profit off of natural supplements but turning them into an artificial mess.
Acquiring more folate (not folic acid, which is synthetic vitamin B9) can help with methylation. Getting more folate is very different than taking folic acid supplements, however, some research even suggests that people with MTHFR (Methylenetetrahydrofolate reductase) mutations might have a harder time converting folic acid into its useable form and actually experience worsened symptoms from taking supplements containing folic acid.
Getting enough folate is especially important before and during pregnancy. The period three months before conception and during the first trimester of pregnancy, mothers who get enough folate lower their children’s risk for various health problems. Look for the bioavailable form of folate in supplements called l-methylfolate and consume plenty of foods with folate.
Having more folate in your diet means you’re better able to create the active form of 5-MTHF. Some of the best high-folate foods include:
Beans and lentils
Leafy green vegetables like raw spinach, cabbage, kale
The most important thing to remember is this, humans are designed to reproduce. We have been doing it since the age of the human race. Our bodies are not flawed. Decades ago, we never used to have the heavy pharmaceutical involvement that we have now and we used to rely on our bodies going through the biologically normal stages of pregnancy and birth. It is only recently, that we have been taught to fear pregnancy and fear birth, as if our bodies are broken and they don’t know what they are doing. This only has benefits for the pharmaceutical companies.
If you naturally have a healthy diet, you do not need to supplement your bodies with anything. It’s is equally important to note that anything you put into your body, you put into your baby, so read those ingredients in your pre-natal vitamins.
