Help..! Tmi sore vagina...?!

Claire • Proud mummy to baby Girl ❤️
Hi I'm
35 weeks +3 and the last few days mainly in the evening my vagina has been so sore. It feels like how you would feel after a wild sex session or something .. But not had sex at all since the weekend... Rubbing it seems to help but then it feels worse. Feels sort of swollen. Doesn't help I can't see down there myself. Hubby says it doesn't look too bad though.. Just worried it means the baby may be coming soon. First time mum so no idea. It's 3 in the morning I've woken up in pain. Rubbed olive oil on myself to try and give relief it's helping a little. Anyone else had this ? Please respond if u are/ have experienced this. Xx
