my last period was 12-18-11 me and my boyfriend had unprotected sex and he came inside me on 1-8-12 im confused on when my next period will be but i got cramps like i was getting my period but nothing is happening i had this for about five days and now they stopped. and i found a white glob in my underwear and two small brown spots, ive been feeling bloated also, tired. could this just be normal or could i be pregnant?
