We dtd after 2 weeks. We hadn't been very intimate while I was pregnant as I so exhausted and had m/s the whole way through, so I couldn't wait!!
It did hurt the first couple of times as I had a small tear and it would sting for a couple of hours afterwards.
Maybe start of slow, and see how you feel, but don't feel pressured into it. It does feel really awkward the first time, so prepare yourself for that.
