Hello Doctor, I am 28 year old guy, I had sex on 27th march, in excitement I inserted my penis once without condom, but I wore condom after 2 second. I am scared about those 2 second because I had some precum that time. But I didn't ejaculated inside her. Before sex her last period started on 11th MARCH and never last for more than 3 days. And she got her period on expected date from last cycle, i. E: 8th APR, but this time period last for 1 day only. She did not get on 2nd/3rd day. Is she pregnant? Here I am summing up: 11, 12, 13 March: Normal period 27 March: Had sex (unprotected for 2second then protected) 8 Apr: Period for 1 day only. She study lot at coaching, colleges, and sometime do not take proper food, she take beetroot juice, coconut water, honey lemon water. She eats very less because want to maintain figure, she do rope skipping exercise daily 600 times. And she told me her tummy never aches during periods. Now kindly tell me is she pregnant? Or there is some hormonal imbalance because of food, and hot weather of 40�-42� these days.
