NEED ADVICE😩

I started my period when I was 8 years old and I always had bad cramps in my stomach and lower back,diarrhea and throwing up on top of hot flashes when I was 14 I got put on bc (it stopped my period) but stopped when I was 15 because I started gaining weight 15-17 I went without any periods until after my 17 birthday my symptoms came back and was still the same but around the time I turned 19 they have gotten worse and the pain last for hours sometimes 8 hours at the most it’s the same symptoms but now I have tender breast and headache and sometimes I get sent to the ER and they have to put me on an IV because I can’t keep nothing down and from what other doctors tell me I tend to turn pale... I don’t know what to do me and my husband are trying out have our first baby together I don’t know if I should go back on bc or just continue trying... PS I also found out when I was 18 that I have two uterus so maybe that’s what causing my pain
