Last night I bled ALOT. I really believed it to be the onset of a MS - very scared. After no sleep, few tears my OH and I turned up the EPU centre and they agreed to a scan. Turns out that baby is fine!!! saw him/her kicking away (had the longest legs) and the pregnancy is strong. They found a bloody area of around 5cm around the gest sac and apparently this can be caused by over active hormones - the same ones that cause MS etc. I never knew this could happen.... I have my offical 12 weeks scan tomorrow, so it will be nice to know whether or not this bloody area has reduced. Most of the time it will either drip away, absorb itself into the tissue or the worst case scenario is that the bleed can detach the sac from the wall - however this is very very very unlikely.
