Post-IUD Question

Currently have the Mirena IUD. I’ve had it for almost 3.5 years, and planning on getting it out next spring! Once I get it removed, is it possible to conceive before I experience a period? If I’m tracking my cycle & non-existent period correctly, I’d start my period the week after I got it removed. If we started trying right away, could we conceive? I’m so ready for a baby, but hubby & I agreed to wait until we both finish grad school.
