We?ve been ttc #2 for 6 months but this is our first month using the CB ovulations sticks.
I usually have a 28 day cycle but sods law this month it was 35
I got my positive LH surge on CD16 and we DTD on CD16,17 and 18
I also tested my LH levels on CD17 and it was back to negative
So I?m now on CD21 and if it?s a 28 day month that gives me 7 days until AF is due, if on a 35 day it?s 14 days!
Going off the above information ? would you say I ovulated on CD16 or 17 as one day was positive and the next negative? And when is the soonest I can POAS! 
Also ? I had really crampy pains on my LHS over the days I could have ovulated, which then switched to the RHS and I now have period like pains low and central ? does this sound encouraging or just like AF is on way?
I?ve also lost a little bit of weight ? whereas I gains LOADS straight away with #1 ? any thoughts?
