Are cheapie internet OPKs any good?

[IfAtFirstUDontSucceed]

I seem to be spending a fortune on OPKs and was wondering if the cheap ones you can get online are any good.

I've started charting this month, but still need reassurance from OPKs but I am reluctant to take the risk on the cheap ones if they arent that reliable!

Think they are meant to be more sensitive than "plastic" tests, especially the digital ones!

sorry, just realised you meant OPKs and not HPTs, sorry

I got 30 for about £3 i think last month off amazon. they seem to work fine, i got a positive about 4 days later than i thought i would so found them useful.

still not up the duff though!

Yep they're fab!

I had the ebay cheapies aout 20 for £2 or there abouts (and you can mix and match OPKs and HPTs).

I was trying to a year & 3 years respectively with ds's and only 3months with dc3 who I'm currently pg with. My cycles are slightly irregular so took the guess work out of timing and hey presto 3rd month in and got a bfp!
