I had my first appointment today and I found out I'm only 6 weeks and 1 day. I also was told they did not hear a heartbeat I was told to return in a week to see if there will be a heartbeat or I will miscarry. I'm not sure what to feel or think my Dr was so sure that most likely I will have a miscarriage. Also what has me more worried is that my LMP was on jan 4 so I should be around 9 weeks right??😓

Update I went the following week for my appt and yes it was confirmed that I will be having a miscarriage..that was March 10th...yesterday I went through the whole miscarriage but I felt something was wrong I wouldn't stop bleeding so I was taken to the emergency room..2 dr's did a pelvic exam both concerned that I might bleed to death..I had to go in for an emergency D&C...everything came out good I am now in bed rest..just really in disbelief of it all...🙃
