Before mmc I ovulated cd18. On the cycle I conceived my clear blue didn't detect peak fertility, only high, and I got a blazing positive on a cheapie.
Last cycle was the one directly after mmc and I ovulated cd31 (I know this is common after surgical management). Neither clear blue or cheapie caught the surge though the cheapie was getting darker and it's only that I temp that I knew I ovulated.
Fast forward to today, cd17 and I'm on day 5 of low fertility blank circle on cbd though it looks like the cheapies are slowly getting darker. Will attach photo from this morning.
Has anyone had any issues with cbd being unreliable? I have used them since July 18, always kept the same holder but I threw it away after mmc and have used a different one this time. Sorry for the long post!
