Weird mucus discharge?

Sorry, I wasn’t sure where to post this. This might be gross to some but I got my implant taken out in April but once every month since June I’ve been having this weird discharge somewhat in the middle of my cycle. It’s pretty large, stretchy, thick, and a bit like jelly. I have strong cramps, back ache, and leg pain before it comes out. When I asked my gynecologist about it she said it’s normal and moved on. I understand if a doctor says its fine I should move on but it just doesn’t seem right. Also, she wasn’t in the mood to give good service that day, like she wanted to just move on, so I’m not sure if I should trust her word on it. Have any of you ladies experienced this months after getting your implant taken out?

Today with a tinge of blood.
