not sure - hopefully the bt will help you. I do know that you can sometimes get a +ve OPK when you're pg though, so maybe you did ovulate and not know it. You may have missed the surge, or it may not have been very strong.

From memory, I was still getting +ve HPT after my m/c even though I ovulated (can't access my chart atm, banned myself from FF, so can't check for you). But I was testing with HPTs rather than getting bt, to see when things went back to normal. I'm pretty sure I was still +ve on HPT on CD23, but O'd on CD21.

Anyway - try not to stress about the coffee etc. If you are pg with a new bub, it will have been floating around without being connected to you, so won't be affected by what you've eaten etc. Just make sure you're taking folic acid.
