Hello Pooja I really appreciate your concern and wish you all the best for an amazing experience of your life I am sorry to say but chances of getting pregnant with your description is very very less As your priced started on 4th and you had intercourse from 11 to 14 April Since you had sex before ovulation Intercourse near ovulation increases the chances of pregnancy which occurs 14 days prior to next expected cycle. that can be confirmed by urine pregnacy card test which can be done at home 10 to 14 days after conception or an ultrasound for comfirmation If you can upload me more information like duration of cycle, your age and complete medical history I will be able to tell you more accurately waiting for your reply Thanks for your question Best wishes
