Dear sir, we have doubt about pregnancy. We have doing sex daily. Since last 15 days we have sex without condom. My wife's period date has been 21-22 every month. Now today's 27. But she has not in period time. So how to know .she is pregnant or not. If she is not pregnant. Then why she is not in period time. We both like to sex without condom. But we are afraid of pregnancy. In family planning. We want child after 1.5 or 2 years. So, what to do for this type planing.
