hi i wrote an earlier post saying about pg symptoms and if they are similar to pms.
I went to the loo about 20 mins ago and i had 2 spots of blood on the tissue (sorry tmi) and am having slight - medium cramps on and off, iam 7dpo, could it be implantation or does that happen earlier than 7 days? i keep thinking the

is going to come early because the cramps are so similar. iv been a bit lightheaded today as well. can any one help?
