So last year I had tried 3 different types of birth control. And I am still on the 3rd one, Junel Loestrin. At first this worked great, it cleared my acne and shortened my periods, and got rid of cramps which was the main reason I got on it. Lately I have a period every 2 weeks, which I knew spotting was a side effect but this is like a full on period, and there is a pain feels like in my uterus and it hurts really bad. Should I wait and see if the birth control gets worked out or should I go switch birth control again.
