what the fuuuuu-

I hate my body rn. So my last period was 3 weeks ago. But a week ago I started spotting. Brown and light pink. I've never had issues with spotting before. I'm on birth control. Have been for 5/6 years. So I got super paranoid I was pregnant. Then I started throwing up a few nights ago. I got really really sick. Pretty soon I was just throwing up bile because I had no more food in me. Then I was pooping (tmi) just straight water basically. I felt sooo gross. I couldn't even hold it in because it just came right out. I basically lived in the bathroom for three days. I didn't bother taking any of my pills in this time because I was already super sick, and I knew they wouldn't stay in my system anyways. So now that I haven't been taking them a few days I've started an actual period. Real blood! So I'm just sitting here thinking "Yay I'm not pregnant!" But I still don't know why I started randomly spotting in the middle of two periods. So I looked it up (always such a bad idea) and half of the places I looked basically said STD, cancer, or I've been on the pill so long my body just had a freak out and was like "THAT'S ENOUGH OF THAT. HERE'S SOME EXTRA BLOOD." So now I'm paranoid about that. I'm just freaking out. Anyone on birth control had this problem and it was just their body having a meltdown???
