Hey ladies I'm 4 day before my expected period. My symptoms include:

Waves of nausea

Throbbing nipples

Headaches/lightheaded

Heartburn/chest pains

Cravings/ smelling odd things

I'm also forgetting stuff like as soon as they happen

Had some light spotting 6 days ago

Cramping

I know some of this is PMS, but I also have PCOS. Just curious if anyone has had these symptoms leading to a BFP. I haven't taken a test because I'm waiting to see if i will miss my period. What do you ladies think?
