Confused about pregnancy..
I 19 and I usually have irregular periods since I'm under a lot of stress. I haven't had my period for about 2-3 months.. On February 4th during sexual intercourse the condom broke basically came off with out us noticing. I took a pregnancy test on February 21 or 22 and it came out negative, but latley I have been feeling a bit sick nasuea and small headaches. I can hardly sleep as well. I finally went to the doctor on march 8th and they just took a regular pregnancy test and it came out negative she said they didn't do blood work because pregnancy test they use is really sensative and can detect the pregnancy no matter how early it is, But for some reason I feel pregnant.. idk if its me just wanting to be pregnant that I feel this way.. I'm just really confused..
