So I found out I was pregnant but ultrasound confirmed pregnancy of unknown location. Blood tests were increasing but not doubling. On June 3rd my OB gave me the methotrexate shot to stop growth and start miscarriage. Today June 15 all I’ve been having since then is spotting here and there. Attached is a pregnancy test I took today. Ovulation test was just to check lines. Does it usually take this long for the shot to work?
