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 have regular cycles, please get ovulation study on USG from day 10 of the cycle to know about the day of ovulation.
3. Post menstrual
HSG -
hysterosalpingography, within first ten days of the cycle will be helpful to know about the patency of fallopian tubes.
4. Please get husband's
semen analysis done with abstinence of 3 to 5 days. This helps to know about quality and quantity of sperms.
5. You can simply opt for unprotected sex act on and around the day of ovulation.
6, Lastly, about your concern of seminal fluid coming out of vagina. Normally, the motile sperms start travelling inside the womb and the seminal fluid remains in the vagina. This fluid leaks out of vagina after some time. So you need not worry about it.
I hope this answer helps helps you
May God bless you with a bundle of joy.
Thanks.
