I am 6 weeks pregnant having history of previous miscarriage at 5 weeks. I had spotting at 5 weeks and my doctor did transvaginal ultrasound and found sac measuring 4.2 mm. She said that pregnancy is there but will do another ultrasound at 8 weeks to see heartbeat. I don't feel any pregnancy symptoms just bloating, mild back ache but these symptoms are not constant on and off. I don't feel nausea, sore boobs and many other early pregnancy symptoms. Is it normal and is my baby is fine? Well, I have one 5 years old daughter.
