Should I act on my pain or not ?

So yesterday I had a bit of bleeding (been into hospital before and I just had a bit of sensitive skin that is likely to bleed) so I waited to see if it continued or I had pain and I hadn't
But this morning when I got up I had a trickle of about 2 to 3 tbs of clear/white liquid, and have been having a tightening feeling in my stomach since, I thought nothing of it but it's getting worse and worse and actually pretty painful now 
I'm 26w and just very unsure of what to do any help would be great
