braxton hicks every 10 - 15 mins..

[spinach]

for the last 3 -4 hours...is this normal.. I'm about 32 weeks

Seems a bit unusual to be having them so regular.
If i were you i'd call your local maternity labour ward for advice.
They may want to check that you're ok and not going into early labour.
Keep in touch to let us know how things go.

I seemed to have them constantly with dd2. Worth a check up though.

they're not so regular now... although still getting them and i feel bit lousy... lightheaded and dizzy (but that could be cos i skipped lunch!) I can't go anywhere to get checked, am alone with dd who is in bed. baby is moving as normal, bh are not painful... shall i just ignore it?

Give the hospital a call and they can advise you what to do.
They may even have a midwife that'll come to you, if not tonight, then first thing in the morning.
Do you not have a friend or family member who'd
sit with your daughter?
