Confused with cycles!

I am getting really confused at the moment with my cycles. I came off bc at the end of August and have been ttc our first child since then. I had my normal bleed after my last bc pill and this cycle was 37 days long until i got 3 days of af. My 2nd cycle was 36 days long and for this cycle i was using a clearblue fertility monitor so i could pinpoint exactly when i ovulated with my cycles being so long. I got a high read on day 24 on the monitor but no peak read which means i didn't ovulate. I am now on my 3rd cycle and using the monitor again and i have had one high read on day 10 and 2 peak reads on day 11 and 12 meaning i have ovulated. But as i have ovulated so early in this cycle it will mean this cycle is only 26 days long! Do you think this month is my forst normal cycle from coming off the bc as i know it takes a while? Also do you think i will be able to concieve ovulating on day 11/12? My husband and i did the deed both days so i am keeping my fingers crossed for third cycle lucky! Any advice you can give would be helpful as everything is so confusing.
