Right so im 15 years old and i am on the pill but i forgot to take it one day and had sex with my boyfriend who i am in a very good steady relationship with and since then i have been feeling different, i go dizzy, i have nauchea, i get really bad headaches, urinating more than usual, stomache pains, needing more sleep but i had a period last week, usually my periods last 3-4 days but this time it was different it was a different colour and not as hard and lasted a little longer ? what could this mean, i look at it as i may be pregnant but my boyfriend said i am most likely not and i am scared to take a pregnancy test.
