I guess ur concern is about...chances of having pregnancy by having sex during ovulation..right. well..YES..there is high chances of getting pregnancy u r having sex during or around ovulation. let us discuss about the causes of getting pregnancy during or around ovulation. during ovulation the dominant follicle is rupture n ovum comes out from the ovary, if ejaculation during sex occurs in this period then sperm fertilize the ovum and pregnancy happened.in medical term this whole period is called fertile period(it is from 10th to 16th day of menses during this period chances of getting pregnancy is high). DON T WORRY..RELAX, that s not mean that every women getting pregnancy after having sex during the fertile period. I want to tell u that there is high chances of getting pregnancy during this period. with the above discussion u can try out my suggestions- 1. RELAX..EVERY PROBLEM HAVE A SOLUTION. try to do safer sex like ur bf can use condom or ejaculate outside not in ur vagina or u can take emergency contraception during first 72 hrs after having sex etc. 2. u can wait till ur expected date of menses. if it happens then RELAX ..nothing to worry. 3. if menses not happen then do urinary pregnancy test. if it is negative then nothing to worry. 4. if it is positive then visit nearby gynecologist.He/she can help u. I hope the above information is useful, informative and helpful for u. regards-Dr sudha rani panagar (i can understand ur worries, RELAX..DON T WORRY. everything will be alright)
