Hi pink, my boobs stopped aching a couple of weeks ago (I'm now 8+3) and, following a lot of panicking, I was told that symptoms come and go and you should relish in the times when you're not suffering.
Also people do bleed, and still go on to have healthy babies.
I know this doesn't really help, especially from someone with no experience, but it's all based on what I have been told by others who have been through it all and come out the other side with a healthy baby.
I hope all goes well on Sunday, please let us know how you get on xx
