Hi Dove
Try to keep calm and breath deep when it all gets too much hun, as it is not necessarily a bad thing.
I had spotting/staining from 4.5 weeks right through to about 10.5 weeks. Mine varied from brown to red and pinkish,, but was there almost all the time.
I also had terrible cramping (but apparently for me cramping is normal as i have had it everytime)
If you are worried, I would go to your gp and ask for quantitive HCG tests to be done over a few days,, that way you can see that your lvls are rising nicely, or wether there is a problem.
