am a 21 year old university student. i have a very regular 28 day menstrual cycle. on the 19th day of my cycle i had skin to skin contact and fingerieg but there was no penetration and no ejaculation. i am now 3 days late. i was very stressed at the beggining of the cycle upto the 3rd week but i am now very ok. am not on any medication and i havent noticed any unusual symptoms except some watery discharge. wat are the chances that i could be pregnant? am very worried please advice.
