Hcg has th


I have taken 5 pregnancy test including a digital all came back positive. In prior the first two I took I went to the doctors and their test came back negative went to to my blood work the next day, my hcg is at 14? Is that considered pregnant I thought it had to be at 25-50 ? Has this happened to anyone before? I took test and I considered myself really early since I just had my period July 6th and I’m spotting.
