I am 22 years old. I had an intimate moment with my boyfriend on 6th August but we didn't have any sex. I am virgin and maybe just maybe a little bit of his pre ejaculate touched my outer vulva. Later he fingered me a bit. I felt mild lower abdominal pain after 1 day. But now from yesterday, 15th august, I am experiencing gas, digestive problems and frequent urge to urinate. There is also some pain along the waist line that comes and goes mostly during the morning hours We are dead scared. Is this a sign of pregnancy? I took a pregnancy test on 14th, it come out negative. However my periods date is due somewhat around 18-21 August. What should I do?
