Pains....

Justina
I'm not sure where to post this so don't get mad. I'm a FTM with twins I'm 12 weeks +2 . But before I got pregnant a year an half ago I started having these pains on my right side where my ovary is. I've been check constantly but every time I go to the hospital they never find anything or the pain just magically stops everytime I get to the hospital. I never used to be like this until a year an half ago an I really don't know what to do or what's causing this . I don't want to put my babies in any danger or have a miscarriage because of it. The pains came back I've been having them on an off for about a week now and today about 30 mins ago I got them again and they feel just as bad as when I wasn't pregnant. I really don't know what it is and I've been to specialist. I'm not sure if I should go to the hospital right now or just wait it off an let the pain go away. Any ideas what it may be or advice . I'm out of ideas on what it is an done my research. I'm not sure if I should go to the hospital
