3DPO with new meds

According to my app I ovulated on the 14th. I started metformin on the 6th and I'm supposed to start letrozole on the 3rd day of my period. My last period was December 26th and lasted a week. My next one is supposed to be January 28th.

I'm 3DPO and for 3 days I've had food aversions and now getting twinges/cramp feeling on the right side of my ovaries area.

Anyone else have this happen?
