i need some Advise! Please!

My period happened APRIL 13. until now no show of AF. All my PT came negative. Today, we went to my OB. take ultrasound and He said, there’s a small egg that didnt grow that’s why my period came late . Then He give me a PILLS to take for 7days “PLANOVAR TABLET” to start my period.

My instinct tells me dont take the medicine, just wait until AF come. i felt im pregnant but i dont want to stress myself to think i am because all the result is negative. but back of my mind im still hoping. its been 8weeks i guess, No period, negative Result of PT and negative Ultrasound but the doctor only saw a small egg that didnt grow.. Please help me who can relate about my situation to clarify everything. Because my body tricking me so badly. 😔😫
