Hi there, I have understood your concern. I will suggest you the best possible treatment options.
1 ) First of all do not panic.
2 ) As you might be aware that in a woman with regular cycles day 10 to 20 of the cycle is the most fertile period of cycle. If you have unprotected sex act in this period, then she stands chance to get pregnant.
You can get ovulation study done from day 10 of the cycle. This will help to know the day of ovulation. You can simply opt for unprotected sex act in and around the day of ovulation, or opt for IUI -
intrauterine insemination, on the day of ovulation.
3 ) Also , you can get her post menstrual
HSG -
hysterosalpingography done, to know about the patency of the fallopian tubes.
4 ) Please get your
semen analysis done to know about the quality and quantity of sperms.
With normalcy of these reports, most of the couples conceive within 8 to 12 months.
5 ) I will suggest that she should opt for a healthy lifestyle as you have mentioned that she is a bit weak . Please opt for a healthy diet and regular exercise regimen. Include more portions of fruits , salads and vegetables in daily diet. Drink plenty of water in the day. Avoid deep fried foods, bakery products and refined sugars. Use of vitamin B 12 and
Folic acid supplements at least 3 months before you plan to get pregnant. This helps to prevent many problems during
pregnancy and delivery.
I hope this answer helps you. Thanks.
