Pregnancy scare...help me understand

R

So last month of March 1, 2018 I had a miscarriage. My baby had stopped growing at 6 weeks and 6 days. I had to take medication to expel everything out. I was told to wait at least 6 months before my SO and I to try again when we were ready. I already had my first period this month and it seemed pretty regular just excruciating cramps, but other than that pretty normal. I typically bleed for 4 days and have a cycle of 27 or 28 days. My question is if I’m calculating correct I should be in my fertile window, right? Also, my SO and I kind of had a moment early this morning and we had an oops in which he didn’t pullout since we were really in the moment🙊 Is there a chance that I can get pregnant again this month if my calendar says I’m on my cycle day 10 of my fertile window?? Not that there’s anything wrong about getting pregnant again, but I rather just wait the 6 months to recover internally and emotionally. I was going to take birth control next month since I wanted to see how my cycle would be this month, but since we had the incident occur today I’ve just been wondering if there’s a chance I can conceive again 5 days before ovulation day🤷🏻‍♀️
