Last time I had a period was Oct 2nd. About two weeks ago I had unprotected sex where my ex ejactulated in me, a couple days later I started to get cramps, real bad headaches, started to feel achey, and sick to my stomach. I went to the hospital last week for the headaches I been having. They gave me a pregnancy, but it came up negative. I am now 4 days late for my period, do think its too early for a pregnancy test, or are these signs of being pregnant?

It's possible that you're pregnant, but most women do not get a reliable result only 4 days late. Of course you can test now if you want, but if the test is negative don't assume that you're not pregnant.

If and when you do test, use first morning urine. If the test is negative than wait a week or two and test again if you still haven't gotten your period. If that test is negative than wait until your next period is due. If you miss it, than test again or see a doctor for a more accurate blood test.

Good luck.
