My last period was on 7/11 & lasted 4 days. I am always on time. But last month I quit taking birth control pills and now I'm 4 days late. I'm not sure if my delayed period was because of my birth control pills or Im pregnant. The days I've had sex in July (after my period) was 16, 19, 20, 27, 30. This month it's 5,6 and the 10th. Should I test or is it too early?
