Hello, I would be happy to help.
First, you need to repeat the pregnancy
test in 1-2 days. If it is actually positive, you need to immediately call your doctor to be seen.
For the very same reasons that your left tube was blocked, you are at risk for a pregnancy in the right tube. This is VERY important to sort out early in a pregnancy.
With regard to the Lupron
, you can get pregnancy the next month after it wears off. So if you had a one month shot on 7/24, you were at risk for getting pregnant probably in mid-Sept.
I hope this helps - DR TIM
