Some advice would be appreciated

On Easter I started my period, and throughout the day the cramps just got worse as the day went by. I went to bed around 10 PM that night. I woke up around midnight in sweat with jabbing pains on the left side of my stomach (not cramps) just pain that felt like someone was just stabbing my insides. I called my friend and asked if she would meet me at the ER since my boyfriend was asleep for work that morning, and she met me. Well, we went in and they took blood and a urine sample, and pressed around on my stomach. They gave me an IV bag and pain medication through my IV. They later came back and determined everything to be fine and sent me on my way, and told me if I felt the pains getting worse, to come back. They told me to take ibuprofen or tylenol to keep the pain from coming back. Well fast forward to yesterday- right now I've noticed myself bloating like crazy! I'm still feeling those pains coming and going, but ive been keeping them in control with tylenol. I never get this bloated. I'm not slender by any means, but my stomach has never poked out this much before, even on my period. I'm also bleeding more than what I usually do. Does anyone know what could be happening? Could this just be normal, and I'm overreacting? I was 176 lbs on Easter, and as of right now 04/23/19 0421, I'm 182 lbs

**I'd also like to note that I've been going to the gym and eating fairly healthy, except the occasional carbs.**
