I started my first pack of the pill exactly 2 weeks ago because of heavy periods and cramps. On my second week of the pill I have been getting pains in my tummy/pelvic , and I am wondering is this normal? They feel like period pains and I don't know if this is something I should worry about, I am also worrying and wondering about when I finish my first pack of pills when will my period come? or will it even come at all? and what happens if it doesn't come? Please help me with both of these questions they are making me worry a lot and they are starting to stress me out please help
