I'm pretty sure I'm pregnant. My breast have went up a cup size, breast are really sore, bloated, have gained 7 lbs. in a month, back hurts, peeing a lot, waking up in the middle of night to eat a little bit and to pee, I was supposed to start today but no period. Spotted yesterday but haven't started. Did pregnant. Test but was negative. How long should I wait before testing for positive?

Maybe give it another week and if still no period try another test at that time. If negative, and you still feel that you might be pregnant, either see your doctor for a blood test or wait and see what happens when your next period would be due. Some women will skip a period for no apparent reason.
