Hi, I'm 4 weeks pregnant with my second child and after 2 miscarriages at 4 and 5 weeks.

After the first miscarriage I had tests done. I was anaemic, low vit D, low zinc and high homocysteine levels. I also found out I have the MTHFR gene defect.

My first pregnancy was conceived easily and went well until about week 36 when the placenta began to fail and his birth weight didn't budge past 2.2kg. he was induced and labour went well and he's a happy 2 yr old now.

So now my doctor put me on clexane and progesterone pessaries, to prevent miscarriage. Reading the leaflet in the medicine box, it says not to take it if progesterone levels are normal. My blood test at 4 weeks said progesterone was 53 points. Is that normal range? THe doc said it was high, but didn't say whether it was normal. SO I'm concerned that taking progesterone pessaries when my levels are normal might be dangerous to me or the embryo. Could you yo give me any info to feel more at ease about taking them? thanks : )

Hi Robyn We do have a page on Hormone Testing. You'll see your level is good, it can range from 11.2 - 90.0 ng/ml. Unless Australia uses the SI system of measuring, which I think it does, in which case your level is on the low side, the range being 35.6 - 286.2 nmol/L. There are always cautions about using progesterone in pregnancy, none of them with any foundation. The higher the progesterone level, the healthier the baby. You might like to read this page here. We also have a page on Pregnancy you might like to see. It doesn't surprise me your vitamin D is low living in Australia. A lovely sunny country but with a daft government policy about covering up when in the sun. Nothing could be more dangerous to our health, we need it to make vitamin D. It's vital for pregnancy, the growth of the child too. as you'll see from the papers on the pregnancy page. Has your doctor given you anything to reduce the homocysteine? It's easy enough to do, there's a list of nutrients to take on our Inflammation page. Both progesterone and vitamin D naturally prevent platelets aggregating, you don't need the heparin to do this, providing you have enough of these. Take care Wray
