Hi. Im getting married this 20 March. Im pretty sure im getting my menses on 8 march and of course in two weeks will be around 21,2,23 march. My fiance already booked a hotel on 21 march for our honeymoon. I think i wil be pregnant if i will have sex these dates mentioned above. It will be our first experience in having sex and we dont want to use any contraceptives! Please give me an idea.
