I took the Depo Shot and have been on it for two months. I’m not due any time soon to get it, I still have a month, but every time I do research they don’t even LIST what happens if you DO get pregnant on the Depo. Like its all unspoken...I got a packet from my doctor saying its only a .3% chance that true? I had intercourse recently 2 days before my period, of course the depo shot messes that up and last time I had my period it was for 3 weeks, he hadn’t cum and hadn’t cum at all that day. I made him stop cause I got freaked out. But then I read up on pre-ejaculation…can I get pregnant from that? I mean does the depo shot stop pre-ejaculation or just normal sperm? Thanks for reading. Also I heard your supposed to take a pregnancy test 17 days AFTER you had intercourse…but the label tells me to take it the DAY after you miss your period…so when do I take it?

Welcome to ehealthforum,
Depo shot works in preventing pregnancy after about 4 weeks of taking the shot. It should give you protection against pregnancy. The hormonal dosage in it can mess up your normal hormonal pattern, and you might take some time to get adjusted to it. Pregnancy can occur with semen ejaculation as well as pre-cum (it is known to contain sperms), when you have intercourse close to your fertile days or during your fertile period (and if you are not on any form of birth control). Urine pregnancy tests usually start being positive after about 1 week of missing periods. Sometimes urine tests can show false negative results too, because urine pregnancy test kits are calibrated ones, so they show positive results only after the hormonal levels in urine have reached a certain level. If you suspect to be pregnant, visit your doctor/gynecologist for examination (to confirm pregnancy related changes/signs in body) and a blood/serum HCG level test (to confirm/rule out pregnancy accurately). If you get pregnant while being on the Depo shot, chances of miscarriage, premature labour, feminization of male fetus, low birth weight of baby, defect of male fetus urinary tract formation, infant and neonatal mortality rates increases.
Take care.
