Hello ladies! Looking for advice and experiences. Slight tmi but it is what it is 🤷🏽‍♀️

Currently 7dpo, according to my Glow app. Had sex 10 days ago (3 days before O) and for the last 3-4 days I’ve had a very heavy feeling uterus. Anyone else have this before? If it’s pregnancy, I feel like it would be way too early for my uterus to be enlarged and I don’t remember this with either of my other pregnancies. I have a doctors appointment to check it out today
