So I had my son in October last year. My periods have been a bit random since. I had a miscarriage in March this year. I was only 6 weeks along, but ended up in the hospital with heavy bleeding. My periods are now even more irregular. They are every three weeks, rather than the normal 4, or they are short. My last period was only 3 days and the month before that 4 days. Before I had my son, my periods were always at the same time every month and lasted exactly a week. Has anyone taken something to help with a similar problem? It makes it hard to predict ovulation. I don’t want to be using ovulation tests every month.
