Have you ever felt pregnant just a few days after having sex on your ovulation day? We're not trying , but I had been so busy last week I never check to see and realized my husband and I had sex on our ovulation day. I only paid attention now because it's been 4 days, but I've been feeling crampy, extra tired (for no reason, Im stay at home right now) and nausea . Last time I felt pregnant we were but i miscarried at 5 weeks, so I knew I was. I am a bit of a worrier though so it may just all be in my head (I could have a stomach bug for all I know!) . But has anyone else just FELT pregnant right away and were pregnant ? Or am I nuts for being worried?
