Question

I am 35, and at age 34 had a healthy baby girl. However- when I got pregnant with her, I kept spotting for a few weeks. My doctor put me on prometrium until week 14 because when she tested my progesterone at week 5, I was at a 7. After one week of Prometrium, I went up to a 40.

I have been tracking cycles again to have another baby, but I do not make Cervical mucus (at all) and I have never had a positive LH Surge show up on a OPK. I used the bbt method this time and on Friday noticed a dip in temp of almost a full degree!(day 14) That night was our night to TTC. The next day I took prometrium and was still continuing tracking BBT and OPK. After taking the Prometrium, all of a sudden(for the very first time in months of tracking) an LH surge showed up yesterday morning. I am assuming the Prometrium has something to do with it because I had never been on it before the first pregnancy and never had an LH surge (though I still got pregnant.) So--- my question: what is more believable, the dip in temp on the bbt, or the LH surge (day 16 of a 30 day cycle). Can Prometrium give a false LH surge presence?

Answer

The LH surge is more accurate as an indicator of imminent ovulation. Prometrium will not cause an LH surge; although, if given in excess amounts can inhibit it.

Since you had low progesterone before, it would be worthwhile to see a physician or other medical provider who is well-versed in NaProTechnology to evaluate you. Progesterone or HCG supplementation may help you conceive and avoid miscarriage.
