Hugs. I had 2 bright red bleeds, both small that happened 2 days apart at 11 weeks. My DD is now 4 months.
At the time no one could tell me where it came from and suggested it could be a little blood vessel popping, or from DTD (which we hadn't).
I know it's hard not to stress, try and relax and if you get anymore call your care provider and try and get an us for your own peace of mind.
