NoahMama, It all depends if you had unprotected sex since you stopped your birth control pills. The bleeding on Feb 10 to 13 was most likely the normal withdrawal bleeding that you experienced when you got to your inactive pills. That should not happen after you get pregnant.
If you ovulated on Feb 9, you should have your next period 12 to 16 days later, but most likely 14 days later. This bleeding in between could however mess that around.
Your actual period will most likely also move (not be on Feb 26) because you were on birth control. Birth control hormones will regulate your cycles very precisely so that you can pretty accurately know that you will bleed on Feb 26. It will take some time for your body's own hormones to take charge of your fertility again and determine your new cycle and menstruation days.
Best of luck TTC!!!!
