Thinking of you hun I've been exactly where you are, lines were so faint and my beta results came back as 18 they told me the worst but I still kept getting lines so I begged my doctor to at least do a repeat and she finally agreed and it came back 63 she said it's still low Carla so literally in limbo had another blood test and went up to 360 something then she said wait a week for 1 more repeat which I did and it came back 1240 and now I have a beautiful healthy 2 and half year old, good luck hun, my guess it's a new pregnancy them numbers are amazing please let us know how you get on with scan xx
