Well for about a month and a half I has bleeding like every other week like clock work. I went to the doctors and they said nothing was wrong and I may have had an infection causing me to bleed. I had unprotected sex about a week after my last period. Then about two weeks ago when my period would have normally came I got all the PMS symptoms with no period. Last week I wiped and there was discharge with a little pink in it. But nothing but that. I wiped and it went away. But other than that I don't really feel pregnant.Except that I'm really hungrey and everything upsets me. And today I got an awful cramp reallyy low in my stomach. I'm really confused. Could I be pregnant ?
