Syrah,
Don't panic. Relax n Zen k. Now, monitor the colour of ur stain, if it is light brown then its likely implantation bleeding considering that u r 10dp ET. That's considered good. Agree with the sistas abt the cramps. It could be ur uterus adjusting for ur BFP (YEAH!) For now tok to embies, tell them cling tight tight. Take more warm fluid. No cold stuff hor. four more days to BT right?
