Hello
Thanks for your query. Normally bleeding results during first intercourse due to tearing of a Hymen which is some what painful so it is always advisable to refrain from having intercourse for two to three days till it heals.completely.
As regards your query about blood group of your future child on the basis of the blood groups of both of you that you have posted the blood group of your child would be one of these four possibilities.

O --ve

dear Suresh
if your wife is virgin or even her vagina is not dilated or not exposed to previous sex or otherwise even in normal lady vagina is not that much dilated and if lubricant not used or thick penis with repeated strokes without four play may result in bleeding if bleeding less and partner is bearing it then with some relaxation inbetween without hurting her with her consent intercourse may be continued but if too much or partner is not bearing it stop if for relief to partner but if its is already menstrual bleeding sex may be done but it will spread blood over penis and even over her thighs and bed so may spoil you both and you may afraid of some injuries or even it may enhance bleeding or cause infection so sex during mens should be avoided but scientifically may be allowed with proper hygenic care and post coital care.
your child may be O or B it will dependant whether u and your partner is homozygotic for blood group B or O .
