Technically? Depends on your provider. Mostly, they don't like you to have more than 4-6 an hour. In my case? I don't call unless they are *real* contractions. Since this is your first, that's hard for you to tell though. You should call if you are unsure or concerned. I personally have anywhere from 10-12 an hour with no concern.
okay thanks they usually arent painful, but i have lost bits of my mucus plug already and have a little bit at a time for the last four weeks. None blood tinged just a gooey green mucus stuff. It really freaked me out at first. Also I a pretty sure he is head down. But not engaged I dont think. But once again I just dont know. I see my doctor on tuesday hopefully he does a more in depth appt.
