Unfortunately it is different for everyone so there is no way of knowing. It could take a couple of months to get back into your normal cycle or it could happen straight away. For me though, I had my period 5 weeks after the bleeding stopped. An ovation test may help. In terms of testing now, I would take one a week until either get a positive or period starts. Good luck, I really hope you get a positive result.
AFTER BOTH MY MISCARRIAGES I HAD MY PERIOD 3-4 WEEKS AFTER
