should I be concerned???

So for the past months I have been kind of irregular when it comes to bowl movements. And I eat quite a bit throughout the day.. my stomach has been hurting, and I tend to feel almost a bubble like sensation. However, It's very difficult to just "go". The past two days, the times that I have been able to "go" It takes me a while and I have noticed I bleed. It's more so blood and blood clots than stool. I'm getting a little worried, and I'm not sure f I should see a doctor? Any suggestions? Has anyone else had this? Please let me know!
