Friends, I charted my BBT through my entire pregnancy and noted some other milestones along the way. I see (and myself had) a lot of questions about BBT after HPT+, predicting MC, etc, so I hope this can help someone out. While my BBT did dip below CL a few times during the pregnancy, it did not stay low for any extended time. During my MC cycles, it also did not get low but my MCs were "missed", meaning I did not cramp or bleed; they were discovered via ultrasound. Progesterone supplementation (like I had) also does increase BBT, which can be seen on my chart.
Because of several early losses, I took progesterone suppositories for the 1st trimester after HPT+ and had NIPT testing at around 11 weeks. I ended up with extremely high blood pressure in the 3rd trimester that thankfully didn't turn into preeclampsia but did result in induction at 37 weeks. My sweet baby girl was just over 6 lbs and absolutely perfect! Here's the charting result:
