Me and my girlfriend both had sex for the first time twice 1 with condom and 1 with and I only put the head of the penis in for a second before she wanted to stop and she's had a odd feeling in her stomach for 2 day stopped now and has had a loss of breath. We're both sure that no sperm came in contact with her vagina that we can think of we both live in different countries and its the first time we've seen each other in months, could it be nerves as I leave soon and she had a big swimming competition yesterday I really love this girl and I don't want to ruin her life. 

PLEASE HELP
