Hello dear
I understand your concern
If you have regular period of 28-30 days then your fertile phase is 10th to 18th day of cycle.
Do sex daily in fertile phase of period.
So avoid sex during your 3 days period.
Sex during period increase chance of infection.
If pregnancy will not occur then both partner need to
consult infertility specialist and undergo reproductive hormone analysis, USG scan,
ovarian follicle study, HSG scan and semen parameter for female partner.
Specific treatment will require on test results.
You can take
metformin,
clomiphene and
HCG injection for maturation and rupture of follicle.
Avoid stress, take healthy diet, drink plenty of water and do regular exercise
Hope this may help you
Contact further if follow up needed
Best regards
Dr. Sagar
