I rubbed my penis on my girlfriend vaginal surface not put my penis inside her after one month she gets bleed heavily that lasts upto 20 days she tested 25 times on urine pregnancy test kits all times her test results shows negative. She bleed for 20 days her tests is negative 25 times. No tummy change after 4 months suffering from pcos. Is there any chance if getting with pre ejaculatory fluid in this situation.
