So.. just an update. On cd 18 and 19, around a week after ovulation I started light brownish pink spotting but only noticed when I wiped. It only happened for these two days and stopped. Also my vagina was extremely dry and the walls felt tighter. I guess all this was a side effect of the ec and anxiety. On CD22 I started dark brown spotting and it was noticeable on panty liner. Then last night, cd23 it started intensifying and I started noticing dark red blood. My boobs stopped feeling sore yesterday. And this morning I am having stronger menstrual cramps than usual but everything else normal. My period wasn't due until two days. Is this my period?
