Pregnant week after Mirena removal ?

I had my mirena removed on Wed. Dec 16 and also did the bd with dh that night. On Sat I noticed cm that was stretchy, I checked my uterus and it was open, (that was the first time I've ever felt it open b4.) We also did the bd that evening. Is it possible to have become pg that soon after removal? I know it'll take a little bit for the hormones to completely leave my system from the Mirena. I know I'll get my answer after the 2ww, but just asking, 2 weeks sometimes feels like forever!
