Agree with @Laura, unfortunately. After both my miscarriages, I got my periods exactly 4 weeks after but it took 3 cycles to find my peak LH. I think this is why usually the nhs recommends waiting 2 cycles for the cycle to regulate before trying again x
After my chemical in may I fell pregnant again end of June into 1st week of July then suffered a missed miscarraige at 9weeks in August which was managed naturally no medical intervention other than scans which showed I was ovulating already I've had 2 periods since Augusts mmc and now testing again for ovulation this week but everyone is different noobdy can say when or what is normal
Unfortunately it can take a while for periods and ovulation to get back to a new norm after any kind of miscarraige
