Currently 4 weeks and 2 days pregnant

So the day before yesterday and tonight I have this achy/pressure feeling right in or around my vagina hole lol I don’t even know how to explain it, but it just feels weird and I don’t know if it’s normal? I also went on a road trip and the both times I’ve felt this it’s been after being in the car all day and it’s happened at night. Anyone else experienced this?
