Yesterday, I thought labour had started. How often do contractions just stop???

I had some period pain, low down, in the morning. And I also felt like I was going to be sick!!! It intensified (back pain too) late morning and then at noon - bang - contraction. The pain built, to a point where I had to stop in my tracks - ouchy wa wa - and then eased. Then bubs had a little move. Had a look at the clock. Ten minutes later - off it went again.

This happened for 90mins - every 10-12mins! So I started packing, toddler was asleep! Texted DH to keep an eye on his phone! I thought a shower would help. Then it all stopped!!! Nothing since the shower.

Bhs continued all afternoon but there was no pain - just the tightenings!!

I have period pain and back ache again this morning.

How often to contractions just stop like that? Does that mean the beginning of labour or could I have nothing again for days?

I am due next Wednesday...having s&s on Monday and induced Wednesday or Friday next week...(due to gestational diabetes) .... but would love to go naturally as was induced last time and had not a niggle!! So this stopping and starting is new...but they were definitely contractions.

I have organised for DH to start time off next Tuesday after s&s and have to organise toddler, so...

I would love your thoughts??? Is labour near??
