This is very ironic...you sound exactly like I did about 2 months ago. I'm on my 3rd pregnancy...thought I knew what "real" contractions felt like. Boy was I wrong. I started having BH cont. at about the same time you said you started having them. At first they felt just like BH, but then they got worse and more painful. I went into the hospital only to find out that I was NOT getting dilated, and they were just BH. Needless to say, this happened another 2 times. In fact, I'm 37 weeks now and have been having painful contractions, that I could swear are real, pretty steadily for about 3 weeks now. But by now, I'm leary. I have one more OB appt. tomorrow. If I'm dilated at all, I hope she'll say go to the hospital. Otherwise, I'm scheduled for an induction on Monday the 12th. My frustration level is getting higher by the day. I just feel like I can't trust my intuition nor my body anymore. This pregnancy is NOTHING like the first two. And believe me, we're done after this one. LOL Thank goodness it's a girl (I have two boys).
My advice would be to call your OB or at least talk to your OB nurse. they seem to have the intuition you should have to know whether it's real or not. Then if she/he feels you need to go in, do it. I'd much rather be safe than sorry. Especially where there's children concerned.
Hope that helps. God's Blessings with the rest of the pregnancy! -A.
