Thanks for your reply..... 
my cycles vary a little between 28 days and 32... Last month was a 30 day cycle and I got a positive opk on17 so had day 18 as ovulation day. My lp tends to be about 12 days. This month I just don't know where I am, I usually spot for at least 7 days before AF arrives but obviously this month I didn't ovulate when I have before so im not surprised that I haven't had that yet. I'm on cd 29, my bloods were done on day 22 and were 3 so I'm clearly hadn't ovulated up until then. I've done a opk test today as my new ones arrived in the post aNd it was negative... Which I kind of knew deep down it would be. I just want to know roughly how much longer this cycle will go on for.....?! I guess I'm just trying to hold on to the hope that i may have ovulated a lot later than normal between cd23 and now.
How long have you been ttc? Good luck with your journey
