Thanks so much for your advice, I really appreciate it. I took your advice and scheduled a scan for today, which confirmed a single uterine pregnancy and we saw the heartbeat. So it is a relief! I am currently 6 weeks and 4 days. Is there any chance of things going wrong after seeing a heartbeat? I haven't had any bleeding or haven't had any major cramping. I also haven't been experiencing nausea and morning sickness, but I have had lower back pain, fatigue, and strangely enough throbbing ankle or feet pain now and then. Thank you for your time and help. Regards, N.
