Soph,
My cramps did stop around the same time as the spotting did. The spotting was not EVERY day for the whole time though, it went for like 4-5 days, then eased off for a few days etc.
TMI WARNING!!!!!!!
Also, it was never enough to go onto a liner, only when i wiped, and it ranged from pinkish/red, through to brown. I also seemed to get jelly type mucous that was stained in these colours at the same time too. I found that the more activity I did when i had the spotting, the worse it seemed to get, so I would just try to go easy on those days.
I have not had any spotting at all since then, and bubs is nice and big, and kicking like a mule lol, and they never found a reason in the ultrasounds, so I would say it was just bubs getting nice and snug in utero.
Hope yours is as harmless Soph, fingers crossed for you hun
