When I was younger I heard people complain about their periods all the time and how awful they felt and that periods were horrible. I didn't understand that at all bc when I was on my period I felt great! I actually felt better mood wise on my period than when I wasn't. I felt happy, upbeat, energetic, happy,..you name it. The only normal period symptom I had was bleeding. Now I am 22 and have been cycling for years and my periods are changing. I've been on the same birth control for probably about a year but the last few months I have been moody, emotional, crampy, and just feel like crap. Is it normal for things to change like this? I don't understand why I feel like this when my birth control is the same and I haven't been sexually active
