I think this might be it?

I think I might be in the early stages? Due date today, had nothing until last night when my plug started going. Now today after numerous underwear changes to the point im now sat here in big knickers and a pad I think my waters are leaking as my plug is going and I have really bad lower back ache! Nervous doesn't cover it! I am however about to go off to the shops to get some food in. Trying not to think about it all too much 😂💪🏻
