How fast pregnant after removal Mirena?

hi everyone! I don't know if this is the right place to post this question, so please let me know if this isn't okay. I had my Mirena removed Dec 6, after having two in the previous 8 years (one 5 yrs, the second 3). When I had my Mirena, I didn't have any menstruation or bleeding, but my cycle was still regular (bloating, sore breasts, moody as hell etc), between approx.22-28 of every month. I still have not menstruated, and we had sex days after removal. I have menstrual-like cramps, on and off, my breasts are swollen and VERY painful, I'm extremely tired, and pregnancy tests so far are negative - all the same as in the beginning of my previous pregnancy. Did anyone else get pregnant right after removal of Mirena even without menstruation inbetween? Or is it just my hormones going crazy? I'm going to the doctor tomorrow to get my blood checked, just to be sure.
