Hi, I have been having unprotected Sex with my boyfriend however we are not purposely trying to get pregnant. My last proper period was roughly the 8th of July. On the 1st of august I bled and it was one week before AF should of arrived. I then bled again at the end of that Month. I was here waiting for my period at the beginning of this month and it didn't come however I have started bleeding now.

I took a hpt and that came back poasitive so I told my doctors and they put me forward for a blood test and that came back negative.

I don't know what to think but I have been having a few symptoms in which might also be linked with other things:
-Dizzyness
-Feeling sick
-Bloating
-Urinating more
-Eating&drinking more
My belly button also keeps changing.

Help please.?
