Hi

i am not sure what is going on with my body...I had been regular with my periods (every 28 days) then a few months ago I shifted to 21 day cycle. Stupidly I had unprotected sex but he pulled out; this was 4 days after I had gotton my period. Now I am late and feel like I have pms but it is hard to tell because the syptoms are so similar. I have taked a couple of pregnancy tests all being negative but have still not goton my period. I have been under some stress late3ly and was on some medication for a injury recently(dexamethasone and a anti-inflammitory).

I know stress sometimes can delay your period but I am trying not to freak out here.
