Emma, sorry to hear you have no answers from the lap, but, at the same time, glad that everything looked good. You're right - the NK cells should be measured mid-LP (I think, to determine activity at what would be implantation time). I'd expect the zantac would be safe, but if you're taking other things, I'd call a pharmacy (or your Dr) and ask if there's any interaction or if they're safe to take together.

Curtysgirl, wow! What a surprise! Congrats! Would love to hear how you go with the dating scan!

Afm, had a dark OPK at 2am yesterday and lighter at 2pm, so thinking I probably O'd early this morning. Will see how today's OPK looks (if it's lighter, I've almost definitely passed the surge)...
