Hi,thanks for query.As you had pregnancy earlier major causes of infertility are ruled out.Sperms coming out after relation has not impact on chances of pregnancy.You should visit a gynecologist and go for ovulation study to see whether it is normal or not.There are bright chances of you getting pregnant again.Just visit a doctor and look for any abnormality that you may have.
Wishing you all the best for pregnancy.

Hello;
welcome to HealthcareMagic
You seem to be having a problem of secondary infertility.The part of sperms does come out of vagina and is normal.Presently you can try few tips like:-
-when you have sex do not get up for at least 2 hours after sex so that most of the sperms are retained inside so keep lying.
-Do sex on alternate day from 10 th to 21st day of start of every period if you have a regular periods after 28 days.
You can try these things first and if you do not get result in 2 months you can consult a Gynaec and get these things examined and investigated
-if your husband is a smoker or has drinks few times a month then get his semen analysis done to find if the motility and the quantity is good.
-if you had first baby by LSCS (operation) then you will have to get tubes checked for patency by doing a HSG
-and if required she may even ask you to do a follicular study to see if you have proper ovulation.
Thanks
