OK my boyfriend and I have been trying to have a 2nd baby now it seems like the 2nd time around it's a lot harder. I got off the pill in July and had crazy periods for a couple of months but the last two month that pasted were normal both on the 16th now this month I did not get my period and still don't have it I went to my obgyn's yesterday and did a pee test she said its negative now can that pee test be wrong why would I miss my period I was for sure I was pregnant having some symptoms an everything.
