So my period was supposed to start on January 1st. It's now the 13th and there is no sign what so ever of it coming. I'm usually pretty regular so I'm extremely confused. I took a pregnancy test the 2nd and I got a positive. It was faint though same thing happened on the 3rd.. And ever since then it's been negative .. idk what is going on . What do y'all think ? I posted the tests . And my pee is dark from a med I was taking at the time. Please help I am going crazy
