TTC for 7 months

SM

Hi everybody. Wondering if anyone can help me out. This is my first time TTC and we have been trying to conceive for 7 months. This month I’ve had nausea, cramping, frequently peeing, had swollen breasts for a while but not anymore. I’m two days away from my period but I’ve just noticed that my areolas have started to get patches of darker skin. Just wana know if anyone else has ever had this and if it’s a sign of pregnancy maybe?

Thank you x
