YES finally someone going through the same thing as me!
I was diagnosed with an irritable uterus and had irregular but fully painful contractions since about 34 weeks. Am now at 37 weeks and they've started dilating me, but I'm also having weekly sweeps as they are worried that having contractions for this long can be distressing for both my body and baby.
When this all came out at about 35 weeks, my midwife recommended I ask a consultant at the hospital to put a little scribble in my notes asking for membrane sweeps from 37 weeks, and when I went in a week ago with reduced movements the consultant took one look at me and was more than happy to do this. It doesn't guarantee baby will come early at all, and can often cause more discomfort, but if you're already in pain from this anyways, it can't make it much worse.
A lot of people will tell you to avoid sweeps at such an early stage but the fact is that an experienced antenatal consultant is in a better position to asses what is best for you and baby that strangers on the internet are. Mine even recommended early induction if I wanted it, although I didn't.
Had my first sweep today and it has really ramped up the contractions and pain, but I feel more in control because it was recommended that it would be safer for baby and I to take the risk of being born early, than go full-term and risk possible complications.
In my case baby is a very health weight and developing well and this was the best option for my situation, as regardless what people may say, babies don't always come when they want, and having contractions for weeks before labour actually starts can be dangerous for you and baby. I get sick of people saying 'they must just be Braxton Hicks if you're not in labour'. NO. The midwives call them 'practice contractions' and are often a sign of prodromal labour, which might well be what you're in.
I recommend asking your midwife if she would consider doing sweeps from 37/38 weeks if the contractions don't stop, but be aware she can't do anything without a consultant writing notes in your book, and you can only get that at the hospital.
Keep us updated, as you're in such a similar situation to me and I rarely hear of anyone going through this so will be interesting to see how it goes xx
