Could I be pregnant??

I miscarried on March 2nd and bled until March 6th. I had the feeling I was ovulating pretty quick after the miscarriage.

For a little over a week know my boobs are bigger, feel tender and swollen and my bra is super tight. They don’t really hurt, yet my nipples are pretty sensitive. I feel super bloated and have constipation which I barely have.

Is there a chance that I could be pregnant?

I have no other signs and I don’t know who it all works with my period. They said it was supposed to be here 4-6 weeks after the miscarriage so not sure what going on with my body. Anyone experienced something like this before?
