Do you know what this is?

Hello,
I got a BFP this morning testing on the 29 day of my cycle.
But something strange happened before i did the test.
On day 21 of my cycle i had a very very light bleed, the lightest of pads was more than enough to cope, and this went on for 3 days the stopped.
Whats going on?????????
This BFP comes after a miscarrige in september, so Iam worring about every thing

Implantation bleeding, probably. Did you have any cramp then, too? I had the cramp on day 18, but not the bleeding. It's very common. Congratulations .

Could it have been implantation bleeding? When the egg/embreyo burrows into your lining?

Thanks I'll goolge that.
Yes daisyj i did have some cramps, thanks all for the congrats'
