It’s burns

Yesterday I went to the ER they checked my cervix because they said I was having contractions (btw that I do not feel) they kept me for a while to monitor but they never got better. Since I’m not in pain they sent me home and said if i start feeling pain and etc come back in. I got hooked to IV got fluids so of course I had to pee quite a bit. After she checked my cervix when I went to pee it burned. It has gotten better but today it still burns slightly. This didn’t happen until after she checked me which hurt like hell by the way then I was so tensed up which probably made it hurt worse. I JUST had finished taking macrobid for uti and they still tested me for uti to make sure it was gone and it came back all clear. Sooooo it’s not a uti and all of my test including STDs have came back normal after switching doctors recently. Sooo do you think maybe it’s from getting my cervix checked? Maybe a cut or something? I haven’t had sex in months maybe since 5 months and I’m 9 months next week.
