Lately I've been going to the bathroom more frequently, having headaches and it was about 2 weeks before time to start my monthly again and during intercourse I started bleeding. I opnly bled for about 4 days and now Im seeing like spotting in my discharge like vein like looking... could this be a pregnancy symptom?

Most likely no, but could, normally there is NO sign 2 weeks before your first period ( that you may miss) in fact, missing the period is normally first sign you have.

So it is now just waiting, nothing to do for a while, you have to fist see if you miss period, and if you do, wait 2 weeks after missed period to take test , use first urine of morning, when awake,

I still haven't started. It was 2 weeks after I got off my period and 2 weeks before time to start when I started bleeding during intercourse but it wasn't like a period
