What's wrong with me?

So, I'm like 21 days late for my period, have taken several tests, all negative. Went to the OBGYN today for a checkup and to see what's going on.

The drew blood for a test, because the urine test came back negative.

She said I may have pcos, I have to wait the two weeks for my pap test to come back.

She also suggested that I try the keto diet. To help get healthy, may help me get pregnant.

And all I can think is what is wrong with me? I want to be a mom so bad and it just seems like it's not in the cards for me...

😭😭😭

*EDIT*

OBGYN called me this afternoon.... I'm not pregnant 😭😭

She also suggested I start taking metformin to help regulate my periods, in hopes to help get pregnant.

I dunno.... I feel so discouraged sometimes... like I won't ever have a baby. Like I'm broken, because it seems that I can't do what I was put on this earth to do...
