I experienced that too with internal ultrasounds and speculum. Even fingers hurt for me for ages. I went on medication to loosen my pelvic floor and I also bought medical dialators to help train my muscles to be more relaxed. Easier to follow tips for me is making sure I keep my hips down on the table while it's being inserted (a tip from my gyno) as I find my muscles more relaxed, doing a few keagle excercises the day of, and before hand relaxes the muscles too. I also request extra lubricant because a tiny blob isn't enough for me to feel comfortable. Hope that helps ❤️

The really bad pain is normal, i get it too

If it's pain and bleeding after or during then yes. Unfortunately it's normal. I generally just curl in a ball with painkillers and about 24 hours later, it's MUCH better. If the pain however persists longer than a day or two I'd suggest you contact your doc.
