For the past few days i have notices that i have had some old blood when wiping...

Last thursday we had a BBQ at work - a fundrasier - and i was BBQing for 3 hours straight, i felt sick afterwards and had some cramping.
nothing out of the ordinary over the weekend...
just occasional blood when whiping.

I DTD on Thursday night (dispite all the other girls in our thread putting a ban on it in the first 12 weeks) and there was no problem or bleeding afterward...
Today i have quite bad cramping, in my back and belly and more blood, a bit fresher than previously, but not a lot at all really.

Its the cramping and colour change (not quatity) that is concerning me...

Anyone got something for me???
I cant remember ever feeling like this when i was pg with MJ... also i had no spotting (DTD in the fisrt 12 weeks several time with no ill effects)
