Are you usually pretty regular with your cycles? Have you tried a pregnancy test? That would be the first step. It may be your period is just off and getting ready to start.
If you get a negative result, give it another week and try another test if still no period, or you could see your doctor for a test at the office.

I haven't tried a test yet.. but about 2 months ago I had a abortion sergically.. and I've only had one period since then and it took a while I was thinking maybey that has messed up the cycle? But have got minor hedaces and getting hot flashes?

It's possible, but if there is a change for pregnancy, best to take a test to find out.
