worrying too much?

Alexandria

So in November was my last birth control shot. in Feb 3 months later I went to the doctor and asked about getting pregnant. Like how long will it take, of course he said everyone is different blah blah blah. He said if I've had sex every other day for the nxt 6 months and do not get pregnant then that's when I should be concerned. well fast forward to this month (8 months later) and still not pregnant. I should add that I didn't even start my period until July so "technically" I've only been trying for 3 months. So should I go to the doc and check to see if I'm alright or just wait a couple more months?
