Hey guys

Really weird question. First month ttc off BC, day number 38 of my cycle but I ovulated on feb 12th - 13th (I only followed symptoms and opks, the idea of bbt stresses me out a bit). I’m assuming I’m around 5-6dpo and in the back of my mind I feel fairly sure I’m not pregnant. Maybe it’s the pessimist in me and I know it’s too early, but has anyone else been convinced they’re not pregnant and then found out that they were?

I don’t really have many symptoms. I did have pelvic cramps yesterday and I’ve had sore nipples since the day before ovulation day and that hasn’t gone away. Constant headache too but I also have a neck injury so that’s probably unrelated!
