First period after chemical?


I found out I was pregnant for the first time on 18 Sept then I miscarried naturally on 30sept.. Dr said it was chemical. my periods were always regular but since the miscarriage my AF didn’t show up yet. And no signs of it. but I promised myself that I won’t test before 15 days.. I have read that cycles may become irregular after miscarriages but I also read that chance of becoming pregnant is way too high right after a miscarriage.. I am praying for the second one 🙏
