I am not sure what to do.

I have abnormal bleeding. My period lasted 21 days last month when they are usually 4-6 days. It started early when it usually starts late. I passed black blood when I usually passed red. I am spotting blood which I have never had in between periods. I didn't have any dietary changes or anything. I need to wee and poo urgently which is weird as I used to be able to go hours holding it.

I have already been on a colorectal waiting list for 4 months as my screening test came positive. This new period problem is scaring me as I have never had period problems before.

I went to A&E as I was passing large blood clots near the end of my period. The consultant referred me for a transvaginal ultrasound but I ended up needing an abdominal one instead as I've never been sexually active. I needed to have a full bladder which scared me. I drank the minimum amount of water needed and didn't pass urine for 2 hours as instructed. It felt like torture.

When I was asked to lie down for the ultrasound, I was in so much pain that I couldn't lie down. It felt impossible, it was like my back had stopped working. I tried so hard because I really wanted accurate results. They moved the pillow up for me and started the ultrasound but said my bladder was too full so they couldn't get a clear view. They then told me to go for a wee and come back.

I couldn't control it, all the water came out leaving my bladder empty. They couldn't see anything when they tried the ultrasound again. They then told me they found nothing abnormal so they'll send that to the doctor.

I don't feel reassured about this as they couldn't get a clear view. I feel so angry at myself that I couldn't lie down and that I needed to wee so badly and emptied my bladder completely.

I don't know what to do now. I'm scared there could be something abnormal that's been missed.
