Well, I needed to register and tell you guys my story, because I'm freaking out!
So, let's begin with some details, my menstrual cycle: 30 - 31 days. And my period started on january 1th, 2016.
On january 13th I THINK I had direct genital contact with my boyfriend, I was very wet, and I'm pretty sure he had some pre ejaculate fluids. I never worried because my app said that I would ovulate around january 17th (This day I noticed a lot of cervical mucus)... So let's say I was on my fertile days, but I really didn't pay attention because 1. I thought pre ejaculate fluids wasn't a risk, talking about pregnancy. 2. I forgot I was starting my fertile days... When I checked my calendar and read that it was the first day of my fertile days, I started to freak out... I went online and read EVERY page, about pre ejaculate fluids, about direct contact without any penetration, etc. (Also it was too late to take EC)
So, days passed and I was freaking out, my stress was all over my head

I was still worried and I decided to take a home pregnancy test (February 5th, 23 days after the risk, around 18 days after ovulation might occur), at the place there was only this brand, so I couldn't choose, it was the only brand available (In my country everything work's like that, we're in a economical crisis) I think the name of the test was MediSmart or something like that, it came with a dropper, so I added some drops of urine in the spot (The instructions said 4 drops, and I think I added 5 without trying, I was literally shaking, I don't know if that ruined the test??? was it still accurate?) Anyway, the result came NEGATIVE, and I felt better for a couple days but I was worried I about ruining the test applying one more drop of urine

I don't know, I feel so stupid because I'm worrying about a pregnancy, I had a risk, but I guess that bleeding was my period (it came a day after my period was supposed to come, it lasted 5 days, clots, normal blood, the only weird thing was the brown discharge), I took a HPT that came out negative (that I don't know if it was accurate because I added one more drop

Sorry for the long post, yep, I guess I'm having anxiety issues
