I had an ultrasound at 5w4d for abdominal cramping and they found a SCH. I had no vaginal bleeding at this time. At this time it measured .5cm x .4cm x.5cm. At 8w1d I had another ultrasound to look for a heartbeat and check bleed. They found a heartbeat of 156 which is good. Now my SCH is 2.5cm x 2.1cm x 2.3cm. It has grown significantly. I am now supposed to take it easy and not have sex (for months!)... They said another ultrasound is not necessary. They said if I have vaginal bleeding to let them know. I don?t have to go for another appointment for 4 weeks and they said next ultrasound will be around 18 weeks. I am really nervous because I know SCH increases my risk of miscarriage. Is anyone else going through this?
