My friend is 21 years old and we had oral sex on 23rd June 2018. Her previous periods were from 02-08 June 2018 and till today i.e. 10 July 2018 she didn't have her periods. What are the chances that this delay in periods is due to pregnancy? We didn't have sex. But I fear that cum (maybe precum) might or might not have touched the fingers and fingering might have made precum in contact with vagina. We two are really tensed right now. She started eating papaya from today only. How much effective is papaya in these cases? And for how many days she needs to eat papaya and in which quantity?
