I had un protected sex about a week and 2 days ago. I am on the Depo shot which is the (BIRTH CONTROL), I keep having abdominal cramps and I keep feeling light headed and I feel like as if I have to puke but I won't puke and my vagina is getting tighter. Last time I had sex was about 3 days ago on a Saturday. I've taken home pregnancy test but all came out negative but one had a faint line you had to tilt it to see it and I had a blood work done it came out negative. Could I be taking them to early? Am I pregnant?

You have to wait until your period is two weeks late to test, otherwise you risk a false negative.

My guess is you are testing too early.

I my period was due October the 1st but it never came

You had unprotected sex only a week ago. That's too early to test.

If you had unprotected sex a week ago you would not be showing signs of pregnancy.
You said you are on birth control so when you say unprotected, do you mean a condom as well?

Well I know how you feel I am 18 and about 7 weeks yes it would be too early I took a home pregnancy test when I was 2 weeks and it came back negative give it about 2 more weeks and try again
good luck
