Scared Sh**less

My husband and I had a lot of sex over our anniversary weekend and usually without peeing between sessions but he did pull out every time since I’m not on birth control.. one morning I woke up and used the bathroom and saw a streak of pink and then realized oh shit I’m probably ovulating. So I checked my app and sure enough it was ovulation day. Fast forward to now and I have tender breasts and I’m super tired and hungry and it’s about 6 dpo so I can’t really test yet. Is there like a HIGH possibility I could be pregnant right now? Has anyone had early symptoms like this and been pregnant? We aren’t trying to get pregnant but it wouldn’t be the end of the world. I have an appointment to get an IUD on Wednesday and don’t know what to do about that yet.. Looking for advice or personal experiences! 🙏🏻
