Rant alert!
When did this happen to me? Man. My life and head used to be focussed on things outside my body. The pregnancy and mc last year completely changed all that.
Am now completely and utterly internalising every-bloody-twitch and movement inside my tummy and am convinced every bloody month that I am pregnant. Am totally fed up with it. In the past few weeks have even gone all scientific with it all - mn
, ff, bbt, opk, blah blah bloody blah. [Took a little while to figure out all the acronyms]
Sorry for the rant, but am on CD21 of probably 25 and am going to be gutted if/when I get my period and am totally and utterly sick of this rollercoaster. Really wish I could turn it off. God knows I've tried to be cool, calm, go with the flow, achieve zen... and every month this bubbling excitement hits me at this time, and the phantom twinges fit all the symptoms and every bloody month, I'm crushed when my period starts. 
So, meanwhile, I've dipped into other threads with bits and pieces, and they're very funny and encouraging and I feel like I'm not alone in this, which is very cool. I've discovered more acronyms than the army (!) and have restrained myself from having a big rant. But today I've had a bad day of obsessing about what's going on in my tummy.
Here endeth the rant.
Feel free to share the frustration!
