Doctor said go wait a month but...

I miscarried at 3 1/2 weeks on May 16th. Honestly if I hadn’t been trying and testing so early I wouldn’t of even known I was pregnant or miscarried. I was using Vitex because I didn’t think I could ovulate on my own (I have irregular periods, 2nd month TTC and no cycle) so I ended up ovulating and conceiving. My OB said to wait a month and see if I got a period since i hadn’t had one since trying. Well since I stopped Vitex and didn’t think I could ovulate on my own, we’ve still been having unprotected sex since I stopped bleeding every other day. I decided to take an ovulation test yesterday for the heck of it and it was SUPER positive. We’ve been having sex all weekend! If I do happen to conceive this early after a miscarriage, will it be okay??
