I dont know what's going on

For past 3 days now in morning i have been getting cramps/contractions i dont know, i get a tight feeling in my vaginal area, a lower backpain and lower abdominal pain, i have the urge to push and sorry about this but everytime this happens i have to go toilet and do a number 2, every day i get up these cramps/contractions are getting worse and worse, they come on for about 60 seconds go away and come back untill i dont go to bathroom and do what i have to do but even after i am done i still get pain, whats going on? Has anyone had this as well
