Depends cause i had small bleedin and i had to go to the er and they told me i had a threat to miscarriage but im bettr now though. Sorry to ask but are you having sex? Cause if you are that could be it. And yeah its fine cause since your uterus is growing right now its extra sensative so even sex can cause you to bleed so if you are having it wait off til the 4th month then go crazy lol
yes it is normal i had the same thing happen to me so it is normal now if it gets worse and if your stomach starts cramping really bD GO TO THE DOC
