I have read online different symptoms but what do you guys say from personal experience before a missed period...I'm supposed to be starting mine in 7 days...my husband and I had sex like day one of my ovulation circle which I know there is a real slim chance that I am but I have been having symptoms of course I looked it up and it said these are symptoms but it's ones that could happen just because like headaches feeling nauseous boobs tender...stomach feels funny lol I'm probably just over thinking it..
