I had a medical abortion of32 days pregnancy as my husband and me didn't want.but now we want . But my cycle period has increased from 32 days to 36 days.my first day of mensturation was 3 oct2007.I did pregnancy test today but it came negative. Tell does fingering after intercourse decreases chances of conception and secondly whenever we have sex whole semen comes out from my vagina as soon as we separate.what should I do to keep it inside.

Fingering after intercourse does not decrease chanches of conception.
Second even if semen comes out from your vagina, this is normal and will not decrease the chanches of becoming pregnant. You do not want to keep it all inside and it is not necessary.
I would also like to say that people who have had abortions, might find it harder to conceive.
You need to be patient.
Good luck if your truly ready to become pregnant this time.
