Any advice would be great but basically my cycles are very different every month. They vary between 30-38 every month, so January was 38, March was 34, last month was 36. My periods have been short also (4days) evan that’s a push it starts slowing down a lot at (3days) just wondering if this is normal or maybe I should go have a chat with my doctor? I’ve never had a 28 day cycle. Also had my smear not long ago also so that’s one ruled out. 💫💫💫
