Did you get it at other times as well? I'll definitely tell my doctor. oh I know I got really scared the first few times and wanted to cry cuz I was like it's to early for him to come and he will have all there problems lol.
And no problem :)) I got scared that I was like going into labor haha they did check me 2 weeks earlier than they normally start checking because of it though so I'd definitely still mention it to your doctor :)
