My pre labour started off with having the runs at 35 weeks (sorry TMI) then at exactly 36 weeks i was having regular BH. 37 weeks not so many BH but i started to get hot flushes/night sweats which i have NEVER experienced in my life. A few days leading up i got the runs again and started to feel giddy and just weird. I had DD at 38w1d oh and in amongst all that i was losing my plug.

To be on the safe side i think you should get checked. I always did. I was a regular at the birthing suite weeks leading up lol

good luck xx
