Hi, so I feel like I'm currently going around in circles and no idea what to do.

Last month I had a long period lasting 10 days, off for a week then back on for 8 days, off for 2 weeks and I'm currently on again. This is completely irregular for me but irregular periods haven't been uncommon, Normally it's one small one a month then 2 in a month. Now on my 3rd one in 7 weeks. Apart from that I've had pain during sex for a while but didn't think much of it. On my second period of this interval I experienced stabbing pains in my stomach, pelvic area, lower back and my left leg and they haven't gone since. I've also had bloating after eating, pain with eating, acid reflux,  pain going both toilets, constipation and some blood seen in stool. I've been in hospital and had an ultrasound on my stomach as well as a cervical ultrasound, I've had blood tests, urine tests, been put on painkillers and everything and they've found nothing apart from a small cyst which they've said shouldn't cause symptoms. 

I've been discharged and told to change my contraceptive to a coil rather than the implant but that's about it. I just wanted to see if anyone else has had anything similar.

I'm in great discomfort, had to take time off work and it's affecting al parts of my life. 

Praying for a response
