Hubby and I aren’t trying to conceived but about 9 days after we had sex (last day of my period) I had a brownish discharge. Kinda dismissed it. Now every day for the past 4 or 5 days I’ve been waking up with headaches and just feel super off. My period isn’t due for a couple weeks obviously so I was just wondering if it’s possible that I could have gotten pregnant from period sex? I also have a pretty irregular cycle so I’m never too sure when I ovulate. Thanks!
