In May 2013, I had a MMC at 6w2d. Following the D&C, my cycle took about 6 weeks to return - and my temperatures have been all over the place. Last month, I was unable to identify a clear thermal shift, but I did in fact ovulate because we got pregnant again, however this was a chemical pregnancy, and my cycle started only 1 day late. I had 3 days of + HPT's, so I don't believe this was a false result. Since this cycle started, I switched to vaginal temping. For 3 days, cycle days 15-17, I had a small but clear temperature shift that rose .1 degree each day, and then yesterday and today (cd 18-19), it is back down to pre-O temps and I clearly have EWCM. My CP is high and mostly open, but not quite soft. My typical ovulation day has been around cd17-19 with a 12 day LP, so seeing the shift at cd15 was odd for me - but I'm confused as to what could be causing the odd temperature changes. In March, when we got pregnant, my temperature shifts were textbook, including the triphasic pattern. I'm not on any medications, and only take 800mg of folic acid daily. I temp at the same time every day, and my sleep does not normally get disrupted. Any insight would be greatly appreciated.
