Hi ladies, hope you don't mind me "gate crashing" this thread? I just wanted to say, that after reading thru your posts, I am really moved by your circumstances, and my heart goes out to you both struggling with depression and anxiety, especially in pregnancy.
Pregnancy and childbirth is a real life adjustment anyway, and to have the additional strain of battling depression must be so tough - respect to you both x
As regards your original message asking about the signs of PTL - they aren't too dissimilar from full-term labour. There are the usual contractions, sometimes bleeding and show of waters. The risks however are probably small, and I'm sure everything baby-wise will work out ok for you lovely ladies. Take care, and hugs to you both xxx
