Might be tmi but help me!😞

So I'm a week late and my really having any symptoms but going to test later! 

One usual question for you all!

I haven't had sex in roughly two week but the past 4 days my vagina has been so sore and so painful! I don't what is going on!! I've googled it and obviously that was a bad idea as Google enjoys scaring people but I've also asked around and my close friend said she had this problem when she was pregnant! It was because of the increased blood flow which caused her to be sore for a couple of weeks! 

What do you all think??? 

Please help me!😔
