Good day. I had unprotected sex in March 2013, took a morning after pill, got my period in April. However it was two weeks late in March, we’re now in June I have not gotten my period as yet. I have a brownish/reddish discharge (no cramps), I have constant headaches, I’m bloated and have passing a lot of gas. I took a home pregnancy test, it was negative. I’m worried; I would appreciate any help given.
