1st period after a miscarriage?

Hi! I had a miscarriage last March 22. It was my first time getting pregnant. To anybody who experienced a miscarriage, did your period went back after a 30-day cycle? Today is my 30th day and so far AF hasn’t come yet. Me and my DH did the deed when I ovulated (I based it on Glow prediction and my CM). I’m kind of hoping I’m pregnant again but too scared to be disappointed. So tempted to buy a pregnancy test kit right now.
