My last period was April 22nd and lasted the normal 7 days. I had unprotected sex on the 3rd of may and he came in me. I have been feeling weird, having headaches, sharp pains, loss of apetite. Today is the 8th and when I got up to go to the bathroom and wipe I noticed brown discharge there was no smell and I am worried cause this isn't normal. I shouldn't be having a period again until the end of this month. Any advice or comments would be great.

You had unprotected sex. Of course you could be pregnant.

Only time will tell.
