Extremely sensitive down there

Sorry this is maybe TMI but I’m about 4 weeks and some change and I just used the trusty vibrator and it was the absolute weirdest sensation I’ve ever had. I was SO sensitive I could barely do it. I had to use the lowest setting which I usually use the highest and I came within two minutes. Usually it takes like 15. It was almost painful too, just so incredibly sensitive. Has anyone else experienced this??
