Could I be pregnant

Erica

Me I and my husband have been trying since October with no luck because I have pcos. I’m now 2 days late and I don’t know if I’m pregnant r just late because of the pcos. I did take a home pregnancy test that came back negative. So I’m leaning to I’m just late but all weekend I have been Nauseous and my back is killing me and I constantly have to pee plus I have light cramps off and on . So can any one help idk what to think.
