How soon after getting mirena (levonorgestrel) out do i ovulate? i have endometriosis but had a surgery to remove it ~4 weeks ago

Varies: It is possible to ovulate very soon after removing the Mirena (levonorgestrel). This is partially due to the fact that many women still ovulate with a Mirena (levonorgestrel) in place. I always warn my patients to use backup contraception as soon as the Mirena (levonorgestrel) is out and while they are waiting for their period to regulate.

Depends: on what the rhythm of your prior menses was.
