Am I Ovulating?.. Needing guidance from some veterans.

Mary
Hello ladies! 
I'm fairly new on here, been TTC for the last 2 months! I was previously on a birth control that prevented ovulation d/t extreme period side effects. It was a great way to control my symptoms, and prevent any pregnancies until my husband and I were ready to conceive. My MD told me to wait until we were absolutely ready to discontinue birth control, and that I would most likely conceive within the first ovulation period. That hasn't happened so far. I've read a lot of posts on here and blogs online that it can take 6-12 months following oral contraceptives -- wish I would have known sooner.. 
But, Now is the time, and no luck last month. Missed my ovulation despite spending lots of money on ovulation tests and tracking cervical mucus.
I was hoping this month would be the month! I am in my fertility week, and have been tracking CM. But, my ovulation tests have been coming up as low surge every time... we still have been trying, despite what the tests results present as -- going based off my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> and CM.
Has anyone had any success stories despite low LH surge on ovulation testing? Could I already be pregnant (24-72 hours) and maybe that's why the surge isn't showing? Maybe that's hopeful thinking...
