I am so uncomfortable my period is 3 days late and I feel like my period will come at any moment I'm never late I'm on the 28 day schedule and I don't understand why my period won't come I did have unprotected sex and am trying to conceive but all my tests are negative .every time I go to the bathroom I pray that there's no blood when I wipe but at the same time wish there was so I would know this is driving me crazy why is this happening is anyone going through something similar my uterus feels sore and full there more than usual clear discharge my boobs are huge I have nausea but it's only lingering in the back with no vomiting
