What could be cause my stomach cramps?

I've been have really uncomfortable stomach cramps/bloating feeling since 14/11. They ease off if I sit down but if I walk around a lot they seem to get worse.

I got my period 5/11 and it ended the 9th. It was a normal period. My partner has been working long hours lately so we've not really had a lot of sex this month.

Starting last week I got on and off cramping in my hips, predominately my right.

I don't feel ill or anything it's just really uncomfortable and distracting, especially since sometimes I have to sit down to ease it off and my job requires a lot of walking around. If it hasn't died down by Thursday (my day off) Im going to make an appt with drs just wondering if anybody has any ideas!
