miscarriage or ectopic.

Hello ladies,  I have read several posts on here and feel like I have found the most amazing group on this app. After our first iui, we found out that we were expecting last Wednesday. My levels were only a 14, but they told me to be 'cautiously optimistic' because we were so early. My repeat blood, 48 hours later,is showing I only went up to 21.65. Our specialist told me to go home and rest before our next set of blood work on Monday. He is praying that it is not an ectopic, but said he won't know for sure because it is so early. That word shook me to my core and I'm trying to find someone who can share their experience with me, so I can be prepared. God bless all of you!
