First Beta

So today was my first beta test and it came back positive with a Beta of 70. I will retest on Saturday and hopeufully they will double!! I am cautiously optimistic about the whole thing at the moment. Last night and today I have had brownish discharge which I haven't had before. I am not too worried about that as I have read that this can be a sign of implantation and nothing to really worry about. So I will go with that theory for now!!!
