Hi.  So I had sex while I was ovulating a couple of times. My bf and I are trying to get pregnant. I bled/spotted for one day abt two days ago. I'm expecting my period in two days but I'm having some cramps in lower back and abdomen. Could I be pregnant?  I took a test the the day I spotted but it was negative,  I am assuming it was too early to tell bc we started trying he 14th...  I feel queezy in he stomach,  sometimes dizzy,  urinating often n sleepy...  ??
