Hi Marley

Honestly it is hard to say - could be breakthrough bleeding, or implantation bleeding - I had a small bleed at 5.5wks and freaked - dark red. On the flip side, yes it could also be an early m/c - every womens experience is so different it is hard to generalise what it feels like for individuals. Some people have no pain and start to bleed, others have some spotting and then period type pain which gets heavier.

Good luck for tomorrow, I hope it is just some implant or breakthrough bleeding for you too Post again and lets us know your bloods.

PS you are soooo much more patient than me, you haven't tested since Friday and I would have POAS every hour
