kinda long, but PLEASE BARE WITH ME AND READ🤭💗

Okay so my boyfriend and I had sex July 4th, he came inside me which we are trying to conceive. So since Sunday the 12th I’ve just been having odd symptoms, mild cramping on both sides mainly the right side. It’s just uncomfortable, my breast have been extremely sore. And I’m a smoker which yes I know is a awful habit and I’ve been trying to break that habit, but now when I smoke I get this nasty taste, like it’s sour or metallic. Normally I don’t get that taste when smoking, but lately I have and honestly to the point that I don’t even want to smoke anymore. Well that’s how I knew I was pregnant with my second daughter. So I’m anxious, I went and bought the three pack of the first response test with a early pregnancy test, digital, and rapid test. I just took the early one about an hour ago so my time would have been 12:00pm. I immediately saw a line for test side and got so excited and ran to get my phone, when I came back it just look negative now, has this happened to anyone else? I’m 9DPO right now. Help a girl out! 🤞🏼🤞🏼
