Tmi I guess!!! Earlier today I had ALOT of clear/white slimy clumpy discharge then tonight I have ALOT of white creamy discharge I mean there is a lot of it , it actually soaks my underwear 😩 I am 7dpo also, I've heard it just means af is coming soon but I heard it could be a sign of pregnancy what do you all think?? This pic was this morning now it's just creamy ..
