I'm 34 +2 with 2nd baby, I've had lower back ache like period type ache every night for the past 3 days it seems to start when I get out of the bath but it's been bearable and have had a few twinges down below but nothing major, I have been extremely tired even when I've had a good night's sleep I'm struggling to drag myself out of bed other than to bathe 
then when I woke up this morning I had a headache and have felt kind of queezy and abit off all day (I haven't had any sickness or anything through the whole of my pregnancy), last night my plug started coming away it was the tiniest piece then more again about a hour ago which was abit bigger and also about 3 days ago I had a bout of diarrhea but it was literally once then passed, my first child was born at 37 weeks so I'm just hoping I'm being silly and this baby will stay put until atleast term has anyone had similar and soon gone into labour or is this normal for my stage?
