bummed out

so I missed my period now for a whole month and I'm still getting negative urine and blood test plus my doctor just checked all my hormone levels which they are normal. so they have no idea why I'm not getting my period so now I need to be put on progesterone to jump start my period. I am so bummed because I just want to start trying and now I need to take this medicine for 10 days and then I have to track my ovulation and then hopefully I will get pregnant. I'm just really frustrated has anyone else had to deal with this?
