So 3 years ago I was told I can't have a baby because my tubes are blocked but I didn't loose hope. So today i noticed i haven't got my period and it's been 5 day but I been having back pain but I still took a pregnancy test to just make sure, it's positive. I husband says not to get excited until I'm sure until I see a doctor. Now I'm scared, hope everything goes well.
