is it dangerous?

i had a miscarriage sept 5th i had to take 4 pills vaginally and bled for a good week or two. im no longer bleeding my hcg levels were at 14,000 last week when they checked so they are going down like its suppose to according to my doc but i forgot to ask her if its alright to work out?. i feel good amd want to get my body im shape plus it helps with my depression is it safe??? im just worry that i might hurt something inside and my mom keeps saying that i cant work out or do certain things and she's always up my butt because of it.
