Advice

Hi guys, recently I’ve been experiencing excruciating pain in the suprapubic area, the only way I can describe it is ... something inside the area is pushing out very sharp and it just doesn’t stop then it holds there for around 5-10 mins then it slowly goes then I’m left with something that feels like a period pain, I’m not due on and I’m not pregnant, I’ve had blood tests done and everything has came back clear, I’ve also had an ultrasound on my abdomen and that has come back clear to, I’m getting really worried as it’s now affecting my work and my relationship. This has been going on for over 6 months but this month has got to be the worst so far my gp hasn’t got any idea what it can be but I know its definitely something, any advice would be very helpful
