Chemical pregnancy

Omg I think I've just experienced a chemical pregnancy😭 (A very early MC).. I had a positive pregnancy test and two days later started my period😭😭 I've been reading a I have all the symptoms. I'm so upset. Idk what to do. Idk if I should call my doctor and tell her.. Or if I should just go with my day. 😭 I struggle with PCOS so its not that easy to get pregnant. So devastated!
