Please help me! I have irregular period and took a pregnancy test after 20 days of intercourse, could it be false negative? I had sex 20 days ago, we used withdrawal method and he pulled out long before he came, but I'm still concerned if I could got pregnant. (Need to mention, that he had urinated before we had sex) I took a test today's morning and it was negative. Can it be false negative results? I have experienced cramps, tender breast and nausea during the last couple days, but I also have stomach problems, and i'm pretty stressed out of idea of pregnancy, so it's confusing to know for sure if it was pregnancy symptoms or symptoms of any other thing. Please, help me!

Yes, you could be pregnant, false negative are very common. You need to wait till about 15 days after a missed period, So this can well be 30 to 45 days after sex, to even start testing. 20 days after sex is a bit early to test.

So best to wait and see another 2 week perhaps if you get your cycle,and if not, try another test then.
