First Response OPK

Has anyone used the First Response OPK & found them any good?

I THINK I ovulate on about day 14, based on CM. However I've tried the OPK from day 12 (meant to start day 11 but forgot :doh:). Two days of NO test line at all, then every day since then (starting day 14) has had a faint line which was weaker than the control line - which as I understand it means it hasn't picked up on the luteinizing hormone and hence I'm not ovulating according to the OPK.

Could it be a dodgy test? Could I be having a cycle & AF, but not ovulating? (have had very regular AF since January despite expressing exclusively). I hadn't been checking basal temperature or anythning like that - is that worth doing instead?

TIA,

Belfie - i was using them too and found the same thing. I bought some Forelife OPKs today and did two and both +. I did read on the forelife opks instructions not to use FMU as this can cause a negative result.

Hi Belfie
You could try using the clearblue digital OPK if you're finding the manual type difficult to read. It gives you a digital smiley face when it picks up the LH. It worked really well for me and I fell pregnant the second month using them. They're a bit pricey but I think its worth it. Good luck!!

I read a review somewhere about different OPKs & HPTs. FRER OPK's are pretty useless, but their HPTs are good.

I use Confirm OPKs or forelife are good too. I think the most accurate may be digi ones, but haven't tried them yet.
