Hi Iggy
Am glad you are going to stay around
I think I am the last MC'er from my postnatal thread not to have another BFP, and some are really far along now - you could be back here moaning about MS sooner than you think
My natural MC was quite shocking and scary - like you, I knew something wasn't right and, if I'm honest, had suspected for a while. I am sure yours won't be nearly so bad as it is earlier.
Best I can suggest is what I said before - if you are out and about over the weekend, take a bag with you holding a dark towel, heavy duty pads, some wipes, paracetamol and ibuprofen (or stuff with codeine is recommended too) and a change of bottom half. Try to drink lots of water to replace what may be lost if the bleeding happens quickly.
Mine started off with brown blood and mucusy bits one day, a smear of red the next night, then by lunchtime next day, I had a gush (waters I guess) and then it all happened really quickly. So, I think you will get some warning.
