I was supost to get my period the 11th and it hasent came. Its's now the 17th. My boyfriend and I had unprotected sex last month around the 22nd . So its 7days late. I took a pregnancy test the 15th and 16th and they both came back negative. I'm worried and scared. I don't know why it wouldn't show up. I've been stressed about it these last couple days cause on the 14th I had a very sharp pain in my stomach to the point I wanted to cry and then got very light headed like I was going to faint and I've been getting some sharp pains off and on since. But now its better. Its not like period cramps its just sharp pains. I'm going to try to take 2 more pregnancy tests this week. One today an then if it comes back negative I was going to wait until Friday. But I'm nervous and don't know what to do or think. Could anyone help me out. I don't have any medicaid to go to doctors right now to see.
