I am 18, and have been having sex with my boyfriend now for 6 months. We ALWAYS use condoms, and one has never fallen off, slipped, etc. I am usually pretty regular, and especially so since my boyfriend and I have started having sex. Recently though, I skipped a period, and am nearing when I should be having one again. My last period was the 3 of November, and it is now the 27 of December. I took a pregnancy test 3 days after my missed period, and another one a few days later. I have sore breasts, but this could be because of my nearing period, and I have no other pregnancy symptoms what so ever. Both pregnancy tests were negative. Is there a strong chance I could be pregnant?
I would recommend getting a blood test if your period doesn't come this time around. It is possible for the test to be wrong but the blood test would let you know for sure.
