Hey everyone. I'm 20 years old and not trying to conceive at all. I had sex with my boyfriend when I went to go visit him last Monday and we had unprotected sex- and when I meant unprotected sex, I mean he was rubbing against me and tried to enter but I didn't; there was no penetration. I didn't think much of it, mostly because we used a condom right after and I'm on birth control. However, about three days afterward, I realized I had taken my birth control backwards, start on day 28 two weeks prior instead of day 1. I went to my doctor the next day and she said I should be okay, but I was wary. I've been taking tests the last couple days, and I know that's not how it works, but I've been feeling really nauseous and bloated lately. I don't know if this is because of my messed up cycle and my body trying to regulate itself or, if I'm potentially pregnant. Now back to those tests. I've taken 4 in the span of a week, and I've noticed a grey strip appears in the results screen. I've read online that it's usually just Evap lines or indents since I don't really notice them till hours later. However, I took a test this morning, my first urine, with the blue line appearing right away, and a very faint grey line that only appears in the light. Is it a negative result? I'm actually terrified. I'm still in school, and I really can't focus right now because of this whole problem. Thoughts?
