Babysade, sorry about the BFN. Clearly the pee stick just hasn't realised that you are one of us here and are therefore pregnant. Give it a good talking to and tell it that you'll give it another chance tomorrow. The high LH is certainly encouraging.
Scream, glad your tests are finally more impressive. Clearly you've been pregnant for days but must be reassuring to see the lines agree. I reckon you've just got a dodgy batch. Hope the cramps settle down, and, if they don't, remember they are just getting everything ready for squeak to bed in nicely for the next 8 months.
golden, once AF is over, we just try to DTD every day/couple of days. It is possible to ovulate at any point in the cycle - remember when we had sex ed in school and were told that we could get pregnant during our period, standing up etc? Chocolate fridge cake definitely sounds like a pregnancy craving. In fact, I could do with some as well - so I clearly must be pregnant too.
I can also confirm, with my vast amount of medical knowledge and experience in this area, that raspberry crumble cakes are a sign of pregnancy at CD23. And I know this because I've got letters after my name and everything
