On January I missed my period so I went to the pharmacy and bought a pregnancy test and when I used it it came back positive so to confirm that I went to the doctor he also tested me and came back with the positive result and he said I begin the clinic so last Monday I went to the clinic and they also tested me and the result came back with the second line being faint and the nurse said she thinks am not pregnant so after that I went to the doctor to check what happening the doctor took to the scan and I told me am 16 weeks pregnant so now am really confused about what going on
