Am I overracting...

My Mc was may10th My hcg levels were zero may 30.. going on week 6 of no cycle

I had my ob setup bloodwork for tomorrow to see if I have any hcg in my system... I realize to could take 4 to 6 weeks for a cycle to return or longer but I just want answers.. my breasts were and are sore.... I just want to keep up with my health... I have never had a Mc before and my cycles were a little messed up before I got pregnant...

Is bloodwork a good idea.. then I won't worry as much.... Am I over reacting
