Anyone ever get pregnant on CD 6-7??!

Ca

Sooo.... hubs and I had unprotected sex right after my period on cycle day 6 and cycle day 7. I’m 9.5 months postpartum, I’ve had two cycles now. I was like, “there’s no way to get pregnant that early!” Well today I feel really funky, very similar to how I felt when I implanted with my son. So I did the math and I think I would have had to ovulate on cycle day 6 or 7, and implant at 6-7 dpo (which I did implant that early with my son). So now I’m freaking out because I reallllly don’t want to be pregnant again this soon, I honestly had no idea it was possible to ovulate that early, but I looked it up and apparently it is!!!??? Yikes. I feel really dumb now.
