im 17 i had a baby Dec. 27th. Vaginal birth no complications. On feb. 4th i got a Mirena IUD . and today for the first time me and my husband had sexual intercourse but as we were finishing his penis accidently went up to my urethra and hurt it and i started bleeding and there were a few blood clots, right now im not bleeding as much but it burns. is this something serious? im worried.. should i go get checked by a doctor or what should i do ?
