So I came off the pill early November and have been having unprotected sex with my boyfriend since then. my periods are pretty regular but in January a week after finishing my period I experienced heavy bleeding, nothing like a period, now without that bleeding my period would have been due about 2 weeks ago but when I put that bleeding into the app it said my next period would be due yesterday. I done a pregnancy test a few days after what should have been my period and it was negative, I they done a test Monday, the day before my period was due and still negative. my period still hasn't shown up and there's none of my usual pre period symptoms. I'm not sure what's going on but is it worth taking another test now that it's late again. thanks
