I'd go in and get everything checked out for peace of mind. I just had a full work up at my gyn due to heavy periods, and it wasn't that bad. I wasn't even due for my pap yet.
She ordered blood work to test hormones and an ultra sound and a biopsy. Everything is normal and I feel so so much better and am so relieved! It was worth it the extra time and hassle.
I'm sure it's nothing, but definitely worth getting checked out
