Well it seems everyone has the same fears here. I'm on the contraceptive patch and have used it exactly as it said, 3 weeks on and then one week off when i have the period. Well i was due to start my period on Friday and its now Sunday and i haven't started yet. I know i'm probably over reacting cos its such a short time, but i'm usually on time to the day.The last time i had sex with my boyfriend was on the 25th July, so like 2 weeks ago. How soon would it show up on a test if i am Pregnant. Should i wait till i know before i discuss it with my boyfriend or tell him my concerns?
