Blood leakage from vagina. Do help.

Hi , It's about my Girlfriend . She is virgin . We tried to have sex (with condom of course) but it was too painful for her that I did not pushed too hard in her . But It was very painful I could see in her eyes . She bleed a little and then I messaged that area of her for sometime just to comfort her pain and she felt relaxed . She felt a little pain in her lower abdomen as well .After that when she got to pee in washroom we found out something came out of her vagina with some blood . I asked her what is that and she said maybe the eggs as these were her mensural stage or periods week . The next day she called me and told me that she is all clean down there and no blood spots can be seen on the cotton pad . And then the next day she came to me and I put my finger inside her vagina to check is she feel any pain , but she did not felt any pain but when again I took my finger out ..there was blood on my finger. Now I kinda need your experienced advice on this matter . Kindly do help .
