TTC HELP!! Boobs and cm

Chantelle
Okay guys been having unprotected sex this month it's our first month TTC I'm in CD 27 and AF due over the weekend.
​Here are my symtoms my nipples are very sore and sensitive 2 weeks ago I got a big blue vein on one of my boobs wasn't sure if it was already there so I ignored it today I've noticed one on my other boob that has appeared! And my CM is very watery/sticky also had some sort of cystitis but it never stung when I went toilet just went more frequently but hardly any came out. I don't want to test untill I'm later but what do you all think?
