HI well come to HCM.
Yes there are all the chances of breaking hymen
during this inter course since secretion
came out was pinkish- might be diluted due to secretions or may be partially broken
or little tare which might have given just a drop of blood and due to dilution might have appeared pinkish. This does not mean you will not bleed again during inter course. If
you get injured during inter course there will be bleeding. Thanks
