Hi Doctor , I am Prasanna , 31 year old, weighing 75 kilos. Height:5 ft. 9 inches. I recently had sex with my girlfriend, who is 23 years old. Weight: 52 Kilos. It was dry sex (We had innerwear and a trousert). She too was wearing innerwear and a trouser. There was no penetration. It was just rubbing against each others reproductive organs. I would like to know what are the chances of she becoming pregnant. I am scared as we did not use any protection. Are there any tablets to avoid pregnancy? Kindly help. Also would like to know more about the pregnancy test and how sooner it should be done.
