Not pregnant

Hey ladies been trying to reset my account to not pregnant cos had chemical pregnancy last December 2021 how to change it?.. and my problem now is my period still hasn't come till today.. supposed to get my period last November 2021 so its means I'm now about 3 months delayed but I visited my OB last December no baby found and she said I have a very thin Endometrium that's why she didn't prescribed me progesterone to force my period cos she said it's useless still will not get my period what if I will still ovulate so she told me to wait for my af.. so Im here still waiting.. when will I test again then? Cos now I'm negative. (Sigh 😔)
