Hello. I am 20 year old boy. My ex-girlfriend and I had "intercourse" about 5 months ago, mid-April 2013. She was ovulating, by that time. By intercourse, I mean we touched our genitals together mutually (dry-humping) for 5 minutes in several occasions. I never penetrated her and I had not ejaculated. However, she gave me a ha****b 2 hours before where I came. We did not have any other sexual activities then.

Her period usually lasts for 31-37 days, and she took a pregnancy test at the first day of her supposed period and it was negative. Her menstruation arrived the next day. She took another pregnancy test a week after, still negative. Her periods all arrived during the succeeding months, too.

Today, she tells me she's at Day 40 of her cycle but her period still hasn't arrived. Her constant haranguing and anxiety is making me worried, too. I've been trying to reassure her she can't be pregnant especially after 2 negative tests and 4 consistent menstrual flows. She tells me her stomach feels "bloated" and she can feel something moving in it, and she feels like throwing up. Her work requires her to stay up late frequently this month. She tells me she hasn't been with anyone and we're both technically virgins.

My question is: Is there still a chance she could still be pregnant? I need to reassure her frequently or she'll start crying again.

posted in wrong forum, sorry.
