VAGINAL WALLS VERY SWOLLEN..

I am a regular cervix checker amd think i know alot about the cervix.. however this evening after coming out the bath i checked my cervix to find that it was so high i could only tpuch the tip of it and my vaginal walls had swollen up to thr point I really struggled to find my cervix. Im currently 6DPO. My vagina isnt itchy or has no symtom of anything wrong but was wondering if it could be a sign of pregnancy. Ive also been stuck in for the last 2 days with a real bad cold and a stuffy nose and head. ive also come out in coldsores across my lips. I was hoping to have some advice and really hope i end up at the doctors with a BUMP than ANTIBIOTICS. 😚
