On 1st April, somewhere around 3-4 am, me and my girlfriend where just fooling around. while doing so we both excited and decided to get naked, during that time my penis touched her genital area just for 5sec and she told me to wear my clothes on, and periods got over on 29th of April, and according to her period tracker app, her fertility window opens at 6th of April, we both are really worried and concerned, that she might be pregnant.,
Please help us.
