Advice please

Brytnie • TTC BABY #1
So if my body does what it's suppose to I should get AF Thursday November 19th. When should I test? I had a period October 22-30th first period in 10months induced by provera and takin 1700mg of metformin. This past week I've noticed highly sensitive nipples more than I am use to last 3-4 days my vagina had felt moist but never thought anything of it and last night I checked my CM out of curiosity and had a small amount of white creamy mucus. Any insight is welcomed please
