Hi there I am 7 weeks 2 days pregnant and yesterday morning I noticed some blood followed by a small amount of spotting. I called my midwife unit and they told me to come straight in and get checked out. I had an internal scan and they found a heartbeat but the CRL measured 4.3mm and the gestational sac had a mean of 7.9mm. They've booked me in for another scan in a week and despite there being a heartbeat they offered no reassurance that the pregnancy was probably OK and they just said that the size is much smaller than they would expect for 7weeks 1 day and we should check again in a week. They gave me a print off with the measurements and I've been frantically googling the sizes and can see that 4.3mm CRL would be a 6 week or less pregnancy and there really is no chance it's less than 7 weeks as I know when it happened. I've also now googled and realised the gestational sac is very very small. I've had no further bleeding, just brown spotting but I have no morning sickness, my boobs are no longer sore and I have no pregnancy symptoms. Has anyone experienced anything similar and have any idea whether my measurements are so small that there is probably something wrong or is there a chance it might all be fine. I have to wait 6 days for another scan and I'm going out of my mind a bit. This is my first pregnancy. Thanks in advance.
