I'm 36 weeks and I've been having Braxton hicks for MONTHS now, and for the last two weeks my back has been in constant pain which didn't come with BH before. I woke up today with a pounding headache and back ache, and my son has dropped very very obviously since yesterday. (He's been slowly dropping for awhile now, but this is the most obvious one so far.) The pain has been slowly reaching to my sides, but I haven't felt any obvious contractions yet. I'm getting very nervous!
