Has anyone experienced blood from their belly button?! I had a lap 3 months ago to remove a large endo cyst, the ovary it was attached to, and that tube. For the past year I find dried blood around my belly button and a small amount of wet blood in the button. This only happens once or twice only during my peroid. I've read online this can mean endo on my abdomen and/or my belly button. I'm going to start seeing a specialist very soon. I'm just looking for any info any of you may have. Thanks so much!
