I Had A C Section On May 16th With A

I had a c section on may 16th with a beautiful baby girl. In the last 2 weeks i have been feeling nausea and have only had sex with my bf 3 times (protected of course) since i was 7 weeks. I took my depo 5 days ago and they did the usual blood work before my depo and did not call me(which means i am clear of issues that prevents me from not being able to get the depo) is this something normal??
