ER visit went well! 7 weeks 4 days

Hello guys! So last night around 3 am I had this red discharge. Called my doctor this morning and he told me to go to the ER. They didn’t do an ultrasound but did a urine catheter pelvic exam and blood work. Everything came back good he said my womb is closed. First OB appt is the 28th! That catheter was the worst thing I have ever experienced now my life. Will I have to get another one during my first prenatal visit? I will literally refuse it I promise. I peed all over myself and it feels like I’m pissing FIRE. It hurt so bad I screamed like I was literally in labor. Everything Came back good but I do have a UTI. Doc said it had nothing to do with the bleeding but that some women just bleed and my womb was closed so nothing out of the ordinary. Back to that catheter, I don’t want to scare anyone but that shit HURTS SO BAD. I promise I will not do one again.
