Hi Ladies,
Bit of background:
I'm 29 TTC DC2. DS1 is 13 months and breastfed. DP is in the Military & only home at weekends - great when TTC 
AF returned when DS was 4 months however my cycle is pretty irregular 53, 41, 47, 34 since October. Although pre DS I'd only get 3/4 periods a year max and always had. I fell pregnant in July 2011 & had only had 2 periods that year. He wasn't planned and I was extremely lucky

My AF is currently 10 days "late" however with my random cycle it's impossible to tell, so I'm not POAS till next week while trying to remain calm & unexcited
According to an app I'm using I'm due to ovulate on Monday, however assuming im not pregnant, if I havnt had AF yet (last one 25th April-2nd May) will I still be due to ovulate on Monday?
CM is currently wet (although iv only just started reading about this so not 100% on my monthly changes).
Apart from charting BBT & CM is there a way to track ovulation with irregular periods, or can ovulation happen without AF?
Since TTC im actually embarrassed about the lack of knowledge I have on my reproductive system. I really think this needs to be taught in schools. My sex Ed consisted of putting a condom on a banana & getting shown pics of STIs!
Please help.
Thank you xxx
