I had a miscarriage on December 16th when we were pregnant with our first child. I then got my first period back about 4 1/2 weeks after was normal lasted 5 days. Now I am waiting for my second one to come. Currently 4 days late, but have taken 3 tests and they’re negative. I have on a off cramps. Has this happened to anyone? Does it take a while for cycle to regulate? Thank you for the help!
