Strange period....

Hi, this is my first post ever but I seriously need some insight. Starting last month my periods have changed. Before they’ve been predicable and I had it down to a T but now... I’ve been passing multiple large clots and the cramps, back pain and headaches have been unbearable the first couple days. I’ve never had this problem before and it’s not a birth control issue because I haven’t been in any in the last 5 years. I’m worried now because I’ve recently been trying to get pregnant.

Maybe it’s because I’m in my 30’s now and it’s just my body changing. Who knows.... I can’t get into my OB for another few week so I was hoping anyone else was going through something similar. Thanks 😊
