Bleeding

E

So I have been bleeding/spotting on and off for just over a week. I was 6 weeks on Wednesday. The doctor hasn't been at all worried about it, just said that its implantation bleeding. Still unnerving me though. Had more blood tests then I can count and my HCG level has doubled every time. Just wondering if anyone else has experienced anything like this before? I've read it is quite common in the first trimester. Just need to hear some positive vibes right now 💙
