Hi! I am 18 years old and I am confused if I am pregnant or not. I had my last period on 11 May, 2016. On 9 May, my boyfriend and I had some foreplay. He did not cum anywhere near my vagina. But I don't know, he did touch me down there after that. He says he did wipe his hands. Also, on 15th May, 2016 I travelled from US to India and have been here since then. I am travelling aging to US in 24th Aug. I have had irregular periods, but I am really scared right now. Could it because of travel and changed routine and totally different diet than I had in US?? Please help :(
