TTC #2 after Mirena...HELP!

Tami

My fiance and I decided to start trying right before my 33rd birthday (Aug 10). I'd had no problems with periods and never had one (b/c of the Mirena) in 8 years. I removed it myself with absolutely no problem on the 8th. I spotted 2 days later on my birthday, and truly started AF on the 12th. It was short, about 3 and a half days, which isn't unheard of for me. I never tracked my cycles because I never had any issues. On the 19th, I got a +opk so we BDd twice that day and once the next day. I had 4 days of +opks and on the fifth day I used a digital and finally got a neg on the 23rd. I have so many pregnancy symptoms and had my cycle wrong, which led to a neg blood test today.

Am I out of the running this month?

Could I be IB?

I'm so confused! :)
