Hello everyone. I am very concerned about my situation. I went to the doctors last month on the 18th to get a preg test and birth control (depo shot) They took a test first and it came out negative. They also requested that i come back in 3 weeks for another test to make sure i was not pregnant. Today marked the 3 weeks and my test came out POSITIVE. They then told me i was (5 weeks preg).... It seemed as if i was already pregnant before they gave me the shot. Will the shot effect my baby?
