Hi all. I am new here. I would love any info you might have. 2 days before my predicted ovulation date I thought af had started but it was just a blob of thick white discharge, anyway that night we had sex and then 8 days later I started getting ovary pain on my left side which then after a few days moved to the right side. Now a day before my period due date I have very light pink/brown spotting when I wipe. I use a cycle calculator app which said my period was due tomorrow making my cycle 30 days even though the last 2 have been 25/26 days which is unusual for me as I usually go 30-32 days and my periods are usually very heavy as soon as they start. I have done a pregnancy test which was negative. Anyone have any ideas on what could be happening?
