As I'm over thinking it, getting stressed and cross with DH.
We have been DTD every other day this cycle from day 8, yesterday morning (Sat) day 16 of my cycle I got a smiley face on my OS. However DH was hungover and didn't feel 'up' for the job. Que a heated discussion about TTC#2 and him getting pissed and spending Saturday morning throwing up. This isn't like him at all, he's not even a big drinker, hence why he was feeling so rough.
Will try again later today. Annoyingly we have guest staying so this morning was another no go.
Do you think we've missed it for this month again 
I'm very disappointed and
with DH.
