Help !!!

Chasity

I was recently on the depo shot and was suppose to go 4 weeks ago to get my shot again ! I didn't go because I feel as if it's got my body all types of crazy ! Well I started spotting 4 days ago I spotted for 2 days and then stopped now nothing ! But I am having sharp pains in my lower stomach ! Any ideas or advice ? I'm trying to conceive .
