Hiya Hun,
Spotting and bleeding can be so normal, especially if you have no pain. When I was pregnant in April, I bled and spotted so much and ended up having pain and sadly miscarried. I'm now pregnant again, around 5 or 6 weeks, and I had bleeding then spotting not long after I found out. I completely freaked, but came back on here to have so many members reassuring me. It's important not to freak out, it's so so common. I know someone who bled heavily for 5months!!! Just get it checked out with the doctor. Hopefully they'll do tests! And try to keep calm. I know it's so hard. But I had it for a week (and it wasn't implantation cos id already had that!) and then it stopped about a week ago. Hopefully it's nothing to worry about, but tell your doctor just to be on the safe side!
