Hi. Im 18 And My Boyfriend And I Indulged In

Hi. Im 18 and my boyfriend and i indulged in foreplay (11/02/16). We have never had sex. I am scared that I am pregnant because my period was due 1 day ago but it still hasnt come. He says I cant be pregnant because he didnt even cum and his penis didnt touch my vagina but i cant stop panicking. However at one point his penis did touch my inner thigh area (near my vagina) but we realised immediately and moved. I have slightly sore breats and i feel bloated (always happens to me before my period) but i still havent got it. I took a pregnancy test 1 week after the incident and it was negative. What do I do? Could I be pregnant?
