After miscarriage sex..

Dr told me I could start having sex 24 hours bleeding free, so Saturday night I decided it was okay for me so I knew it was great for him. He did get off inside of me, Dr also said that was fine, but real question is can you get pregnant while not ovulating. I had some pinkish discharge this morning when I wiped then nothing, some minor pain under my hip bones. We are wanting another baby, but maybe I didn't clarify I wanted to wait about a month, or atleast a couple weeks. That's on me not him.
