Gave birth 2 months ago, questions about sex :S very imbarassed about these questions :s?

I gave birth to my beautiful son 2 months ago today. I had a bad labour, had to get induced due to hellp syndrome, and had to get an episotomy and i got a 3rd degree tare. Last night my husband and i tried to have sex for the first time since February. He couldn't get it in me i feel like its stitched shut :s Sorry if this is TMI for some people i just really need to know some things he got it partially in and finished but he pulled out before he came, (i know we should have used protection) could i have gotten pregnant, i haven't had a period yet since having my son, i went in to get the morning after pill but am not able to take it due to me breastfeeding my son.
