I started spotting on friday....It started off brown but sometimes it turns into a dark red or red color...I was so scared I went to emerg and they did a beta and my Hcg tripled in 48 hours....I am still spotting and it is really scary me....I have more bloodwork on Tues and an ultrasound next week...Anyone have similar experiences with this? I am afraid I am going to lose this baby...Think positive thoughts for me
