1st cycle after d&c

How was your first period/cycle after a miscarriage/d&c? My cycles are usually 26-28 days and I normally ovulate somewhere in the middle. I had my first period about 6 weeks after my miscarriage and it lasted 5 days, but 2 days later i took an ovulation test and it was already positive! Glow tells me this means im having a 21 day cycle and my follicular phase this time is only 9 days. That's not a good thing, for those who do tracking you know a short follicular phase means an immature egg will be released. Making the chance of it being fertilized lower and if so, the chance of miscarriage higher. I want to feel like it's just an off month because my body is trying to get back right. But, because I had a miscarriage I can't help but think my body is completely messed up now and I'll never be able to get pregnant again. Im sorry I know I'm rambling now...but does anyone have any advice or can tell me how their first cycle was? Baby dust to all!
