My av cycle is 35 days....Af 16/12-22/12....had +opk on 1/1 +2/1..cd 18 ......temp drop from 36.1-35.1°c...temp started to go up but on 6/1 ..cd 22 temp droped from 36.4 - 35.9°c...and i had light pink spotting on 6/1 and 7/1. Af like cramping . temp stayed low.....on cd 27 temp went up to 36.2 just to drop again cd 29 to 35.7..had very bad cramping like af is on the way. Had loads of ecwm..since cd 28. Decided to take opk...+ today is cycle day 32 and opk still + ..htp - ....still having af like cramping so i recon af will only arive in 14 days..
