tickling/touching sensation on the cervix 13 weeks 5 days

M
Hi Ladies. I wanted to see if anyone knows what it could be or has experienced anything similar. The best way to describe this is a tickling sensation or as if someone is lightly touching or scratching my cervix from the inside. It's not painful and it isn't accompanied by cramps or spotting. Usually last for a few seconds and I have experienced it both sitting and standing. I have felt it about 5-7 times total since 11 weeks. But lately it's been happening more often. I am 13 weeks 5 days today and felt it again. I am just worried that it could be a sign of an incompetent cervix or something. I have been reading too much in Dr. google.
