I had light bleeding (ranged from very pale to very dark brown) from about 4 weeks to 6 and a half weeks. At 5 weeks had some bright red blood too. Also had bad period type cramps. It stopped at 6 and a half weeks and haven't had anything since, and am now nearly 16 weeks. The bleeding was only slight, but was enough to be seen on loo paper and on my underwear, but never really heavy. I wore a panty liner which I changed regularly but only for hygiene reasons, I didn't need to change it because of the amount of blood. Try not to worry, I'm sure you'll be fine! xx
