Hey i had bleeding around 6 weeks and it was because the baby was joiing itself to the wall. They say it the littlest amount of blood, its just the excess that isnt needed anymore as the baby is filling in the gap, then it will start to grow and yer, well im pretty young dont really understand it but yer i had that happen to me about 6 weeks and 2 days.
But i wish you all the best of luck through now and throughout your preganancy.
