No worries. I really can't tell if that is the problem, I can only say what was the case for me.
I did see both NHS and private urogynaes and both sent me to women's health physios. It's like first line treatment.
One (particularly annoying) urogynae did actually say the phrase "I'm not the expert in pelvic floors, I'll leave that to the pelvic health physio".
There is quite a lot of information available online, but if you've got a bit uncoordinated and in a muddle with it all, you might do better just starting with someone to help you make sure you're doing it correctly.
One thing you 100% cannot go wrong with is diaphragmatic breathing. Loads of videos about how to do it on YouTube, you don't need to think about what you should or shouldn't be doing with your pelvic floor, just get the breathing right. It's like the foundation of everything. You add in pelvic floor movement with it after you've nailed breathing, then core alongside pelvic floor after that.
I do have a habit of holding tension in my pelvic floor. To stop doing this (I have pain with tension) I don't actively "put it down", I focus on diaphragmatic breathing which gets it to relax. I'm not very good at recognising when I'm holding it, but I can feel that the pain recedes with the breathing, which means I'm relaxing the muscles in the right way, I can feel the tension release after that, even though I didn't feel it was tense before, just painful. It would be a good technique for ensuring you're completely emptying your bladder I think.
I do now do conventional kegels, but I had to work on relaxing before I could strengthen, it just made everything worse when I wasn't fully relaxing - you can't fully contract a muscle you can't fully relax, it needs to be able turn all the way off and on.
Hope it's helpful info, but I am really not sure it's the right answer for you. Women's health physio would be a sound next step, whether you need to do more kegels or less.
