Ovulation test keeps showing positive

That early test from Kruidvat. There are 2 in the package.
Damn, this is so annoying! Probably too good to be true. Don't assume I'm pregnant.. It almost never happens that I have a cycle longer than 31 days (but that doesn't mean anything either).

@Joyce: I’d think that one at 5 weeks would be less sensitive than an early test, wouldn’t you? I already tried another brand from bol.com (Homedical). As you progress, the hCG should build up if I’m pregnant, right? It doubles every two days, so I should really get a positive test soon, I think...
