d and c

I had a d&c a month ago tomorrow. For the past few days I've had a lot of discharge, it's just white but there's so much.. 
I stared feeling a little crampy today, I've been continuously having sex before I had my d&c and 2 weeks after. 
Is it possible that I could possibly be pregnant again or am I most likely feeling period cramps? Has anyone gotten pregnant after d&c and before their period?
