Back labor or just normal pregnancy backache?

Lu

I'm 38weeks pregnant and having middle and lower back pain on and off alday, few mild pains in the front but nothing major just putting it down to baby moving. I'm not in extreme pain it's just uncomfortable.

Baby number 3 but I have never gone into natural labor so not really sure what early signs I'm looking for :/

I've also been feeling a little dizzy with it, never had any problems with blood pressure.

Honestly really clueless here.

Anyone experienced/experiencing the same thing?
