 [ Symptoms ] if i have only had a herpes outbreak on my butt can it show up on my penis [ Disease ] hi if a woman has a cycle of 28 days then on about 14th [1st day is counted as the day when bleeding starts] day the egg releases so the period between 12th to 20th day is most favourable your friend had intercourse during that period only and there are chances of pregnancy but if she has a severe bleed then it is not probably pregnancy so for confirmation she should get her hcg levels checked by a blood test and also get an ultrasound done hope this helps
