Hey there, I need your help. I took a pregnancy test on tuesday and they cam out negative but it was a full two weeks after the last I had sex. I took my birth control but it wasnt always on time. I stopped taking it last night and now I feel so different and im having sickness and my breasts are tender and you can see my viens. What does this mean? Should i take another test? Do you think im pregnant? Also its been two weeks and plus two days since the last time i had sex.
