So Confused!!!!!!!!help

D

Quick back story:

4 weeks ago I had a d&c.

5 days later bled 5 days bright red

Bleeding stoped

2 weeks Follow up went perfect

3 days later pasted a huge blood clot the size of a hockey puck.

No additional bleeding.

Doctor put me on antibiotics for a week and HCG 75

One week later HCG 25

Today I started bleeding.

Is this finally my period?

My doctor said it could be ....so how do I know for sure!!!

So confused! !
