Sounds like a bit of a bladder prolapse. Is it easier to wee after you have been lying down (like first thing in the morning)?
Whereas by evening times it has had time to 'sag' so weeing may be more difficult later in the day...if it's the bladder position which is the problem.
I have a bladder prolapse (repaired now which has helped a lot) but I never had to push wee out in the way you describe. If it were me, I'd push for an earlier appointment just because if it suddenly got even slightly worse, an inability to get the urine out could put you suddenly into hospital which'd be a right pain in the ass. So better to put more effort into investigating it sooner.
Kind of standing up and leaning forward to wee as if you are skiing, see if that makes it easier. These things will tell you if it's a positional thing.
Hormones can make the ligaments slightly more lax also. So if you are peri-menopausal so you may start to see a worsening of symptoms. If you can get to a specialist women's physio, she will help you do the right exercises to hopefully help somewhat. You might get a very good result after a few weeks/months of proper pelvic floors.
Otherwise at some point you may need a bladder prolapse repair to lift it up a bit (I had this done). Called an anterior repair.
Takes a bit of time to recover, but your kids are that bit older and don't need lifting etc. In the meantime:
don't ever lift anything weighing more than about 6kg (less if possible), so divide your shopping into smaller bags.
Don't lift suitcases etc. Don't turn mattresses or push the sofa around etc. Don't carry a full load of wet washing to the line, break it up into smaller portions.
Try to minimise pushing as in hoovering, so if you have a hoover that you really need to exert a pushing motion, change your hoover to something that glides more easily. Or just don't hoover! Don't do exercise involving running, or jumping or pressing down on the pelvic floor. You might also find that clothes that are very tight around your tummy make it worse, like tight jeans. Constipation may have a knock on effect, as the full rectum may be distorting the shape of the bladder. Good luck with it.
