So before I got on birth control I had severe cramps that were so bad I couldn't even get out of bed and my flow was heavy and it lasted for 7 days. I got on microgrstin 1.5/30 when I was 15 that was my birth control now at 19 my family had a change of insurance and I'm on Junel 1.5 I had called the doctor and pharmacists and found out that it is the same medicine just a different company. This is my first period since being on the new pill and my cramps are debilitating and I haven't slept pretty much all night since I was up getting sick with diarrhea (sorry tmi) and then this morning I threw up a lot which is very very weird for me since the last time I threw up I was 13 and the time before that I was 7 so I'm not sure what's going on and my flow seems to be heavier in my opinion I'm in so much pain I had to call out of work and I don't know what's happening to me
