I’m 33 and trying to conceive for the past year , I saw my ob/gyn and all my labs are normal as well as my husband’s sperm, we have been having sex every other day during my fertile window and this month after a positive ovulation test with an OTK we had sex daily during a 3 day window and the day after I starting to have spotting , not like a period but spotting (dark brown) for the past 3 days now and it feels every time we do everything right I’m always spotting :(
