Loss number 5

Hi ladies.

I have recently lost my 5th pregnancy. I knew I was pregnant and the tests all said no. I had heavy cramping and I could feel my cervix opening and letting something out. When you’re too familiar with the feeling you just know. I only bled for two days and I did a pregnancy test a few days later and it said positive. Then the next day negative. Confirmed my thoughts. I didn’t bother to call the OB because they don’t make me feel any better or give me any sort of answers. I’ve made an appointment to see a new one next month. I notice a pattern. I’m a ballroom dance teacher and I seem to have miscarriages after I’ve done a ton of dancing whether it be student competition or all out social dancing. I feel as though I may not be able to exercise much if I have a chance to keep a pregnancy. Anyone else experience anything like this?
