I've always been told that implantation bleeding may only last a day, and it's usually very light flow or even spotting.
I had a bit of a scare myself because I also thought that once you already have a positive pregnancy test and there is spitting it wouldn't be implantation bleeding. I had a day and a half of spotting and was worried that what wa happening was not implantation bleeding, but I am now 13 weeks and everything is great!!
Even if it goes for a little over a day, it may be okay. :) you and your family are in my prayers! Good luck!!
Thank you for the reply and congratulations! I've read that some women have regular to heavy bleeding before their actual due date for their period and tested couple days after that and gotten a position pregnancy test. I'm really hoping this is the case. Just worried that because it's not a lite spotting that I may not be pregnant. Trying to stay positive! Thank you for the prayers!!
