Pregnancy After Depo Shot: Possible? Symptoms & Timeline

Question
I am 18 and had 1 depo shot on June 21st, 2010, since then i had stop taking any birth control because my boyfriend was at Marine bootcamp, and I wasn't taking any when he came home on Thansgiving for 2 weeks and we had sex at least once a day. I've been looking online at symptoms women experience in the first 2 weeks of pregnancy and I have all but 2 or 3, what I would like to know is how likely is it that I'm pregnant after having only 1 depo shot 6 months ago?

Answer
Dear Tara
Depot shots available in the market should be taken regulary either every month or every 3 months. This is because their effectiveness decline after this period. I am not aware of any preparation that should be taken every 6 months. This should be mentioned on the accompanying leaflet of the shot.

Therefore, if such preparation does not exixt in the US, i would assume that after 6 months of the shot, there is no effect on the coming baby.

Good Luck
