So iv been on and off of birth control twice. Iv gotten every period once im on placebo week and iv had to have my period induced twice because i was on and off of birthcontrol... my period was first induced with provera and i got a period and the second time my period was induced with norenthindrone and i got a short 4 day period and now im nuvaring. Out of curiosity iv taken three pregnancy test and they come out slightly positive and i took another 2 but they came out negative. I also went in for a blood pregnancy test and my result was 0.5 hcg quantity... basically the blood test said im not and i was also told my prolactin is elavted and i might have pituitary gland tumor. Does it sound like im pregnant? Or could it be the pituitary gland effecting the pregnancy test to come out positive?
