5 weeks postpartum and......

Heyy ladies just wanted to see if this has happened to anyone else before.... hubby and I had rough sex and afterwards, I spotted a lil bit and my vagina lips are swollen sorry tmi. And when I went to go pee it burned like hell on the outside when the pee hit the lips... is this normal or has it happened to anyone else? What can I do to help it go away? Tia.
