I'm only 19 but I skip my periods occasionally so I wasn't that worried when I missed mines last month. I have skipped 2 in a row in the past but since I'm 5 days late again this month I thought I might as well take a test even though I always use condoms. I'm a uni student and since I've already bought my textbooks for this semester I only had enough money to buy a cheapie £1 test. The first one was invalid but I think it was because I didn't pee on it long enough. The second one came out positive. The box says it only has 90% accuracy and I don't really have enough money to buy one of the 99% accurate ones (I'm down to £20 for food for the rest of the month). Are false positives common? Is there a service in the east end of Glasgow that does pregnancy tests for free? I know that the sexual health clinic in the west end does them but that's a 5 mile walk from where I am and I don't really want to waste money on a train or bus journey.
