Hi TD, can be very normal. Happens when the placents starts to attatch and hits a blood vessel. I have been having this as well and my US showed up 2 spots where bleeding is happening so to expect to see some in the discharge. But today I have had a spot of bright blood a new bleed? Who knows!!! It can't be changed and I have had it with most of my other pregnancies. Can I be forward and suggest not doing the dance, I know a lot of girls who continued on as normal and were OK, but my doc's have always suggested skip it for the first trimester. Only A thought!!!!
