6w4d Ultrasound

We are still not sure what to think!!! UGH!!! I started bleeding again yesterday pretty badly. I was upset...but figured I would wait for the appointment with the RE today to see what had happened. The bleeding stopped after a bout 5-6 hours. I stayed home from work today and kept my feet up until our appointment. The ultrasound showed a beautiful little beating heart (110 beats per minute) and a little baby measuring 6w4d!!!!! (He/she is almost 7mm today) The RE cannot explain the bleeding, but he did see what appears to be small gestational sack that hadn't been there before that *may* have been a second embryo trying to attach. He said it is possible the bleeding came from that. He said that I am much more at risk to lose this pregnancy than the average woman due to the bleeding that I have had, but that there is nothing that we can do to prevent it if it is going to happen. I am leaving for a 2 week business trip to Australia on Sunday and my doctor will be in Africa (how exotic are we??) until July 8th....so unless something bad happens we will not have another scan until then??? Until then we continue to pray and dream for our little baby who we have wanted for so long.
