Tickle feeling..

Selina • Isaac is arriving May 24, 2016! 💙
For the past few days, I've been feeling a tickle sensation in my cervix area. I'm not sure if it's something that I should be alarmed about. I'm 33 weeks, today. I have a dr appointment on Thursday.. is it something that can wait until then? How many mommies have experienced this? What was your personal experience?
