There is little vaginal bleeding of my wife every day, specially when i make love to her. we are worried about it. she is feeling quite weak.

Should be checked..: Is she having more episodes of bleeding or just when having sex? If she is bleeding frequently it might be that she has developed anemia as a consequence and the reason of weakness. In this case a vaginal infection, pregnancy, or a vaginal/pelvic lesion should be considered. Make sure she sees her doctor for further evaluation and final diagnosis.
