Hi Dannielle,
It's hard not to worry, and I am nowhere an expert, but i would get it checked, for your own peace of mind if anything. I am 6 weeks, 2 days preg with my third, and have been bleeding for the last 2 weeks. However everything seems to be progressing normally. I also bled with number 2, for the whole enitre pregnancy, and delivered a perfectly healthy baby girl so it doesn't necessarily mean there is anything wrong. I also read somewhere on this forum that one woman's ob told her that once they've seen a heartbeat the chances of losing it are minimal, I have no idea if this is true, but it's been a comfort for me. (I have had a scan but it was too early to tell if their was a heartbeat so I'm going for another one next week.) good luck, and try not to stress, I know it's hard!
