36 weeks

Last night I got irritable cramping off and on had about 7 but they were pretty lingering but the more intense they got the worse my back pain got. I slept and woke up with little to no cramping have always had back issues but it's a little worse ever since cramps came n gone. Iv experienced cramping since last week and was hooked up to be monitored and everything looked fine was just told his head was super low and to try to keep him in a few more weeks. 
Iv drank lots n lots of water and baby is very active. 
Opinions anyone ? As a first time mom I don't want any bitchy comments obviously if I knew what to do or what to expect I wouldn't be asking!!
