Weak bladder after birth

So I am now 10 weeks post partum and I am still having issues with my bladder. Most times I will leak when walking, cough sneeze etc but most embarrassingly during intercourse with my boyfriend!! Absolutely horrible. I’ve seen a physio and she advised to keep doing pelvic floors and that my bladder as moved slightly. Has anyone experienced this? If so how long did it take for you to regain control ?
