Spotting while on Clomid

Jasmine • 💙 👶🏽3-6-18.... TTC #2
This is my first round and 3rd day of Clomid  50mg . I was prescribed medroxyprogestrone to kick start AF. AF fully came and gone . But now I'm spotting and mild cramping is the normal .? And is it suppose to be taken the same time each day .? Maybe me taking one yesterday night then again this morning made me start spotting .?
