Hello and welcome.
Well, I can't find the older post anywhere so I'll assume it was posted on another forum and completely outside of Able2Know. No matter.
Okay, hmm, you say your mother is pushing you to get Depo Provera but doesn't know you're having sex? You say:
Quote:my mom wants me to get the shot for me not to get pregnant, deprovera shot
The only logical conclusion is that your mother either knows or suspects you are having sex or are about to have sex. Otherwise, there'd be little reason to get you a Depo Provera shot, right? Hence, that's out of the way or at least it should be.
Let's not tie your getting reliable birth control up with your relationship with your mother. Lots of 17-year-old girls have problems with their mothers. Whether the family is on Social Services or not, or a divorce may be imminent (or not), or Mom is a difficult person or not, girls and their mothers tend to have problems at this age.
Now, as to the Depo Provera: I don't have it, have never used it, but I can tell you that any doctor worth going to will ask you if you are pregnant or suspect you may be pregnant before they prescribe any form of birth control for you. So yeah, you'll pee in a cup (it's a urine test to determine whether you're pregnant). And yes, they'll ask. This is normal, and it's important. After all, the doctor could be sued if you were pregnant and given hormonal birth control (because it has the potential to cause birth defects). I don't know if they do a blood test first, but it would not surprise me. Again, this is to cover the doctor in the event you might be pregnant and also to assure that you are set up correctly. You wouldn't want the wrong dosage now, would you? But these tests are confidential. Unless you specifically tell your mother, you have doctor/patient confidentiality, even though you're under 18. The doctor cannot tell your mother what you're there to do or get - but I'd advise you, if you want your mother to pay for whatever's done, she's inevitably going to ask you. So, if you want to maintain your privacy and not be asked by her, pay for the testing, etc. yourself.
And a pregnancy test is probably the best thing for you right now. Are you pregnant? I don't know, I'm not a doctor. Is it possible that you could be pregnant, even after getting your period? Yes, absolutely, it is possible. But you can get a pregnancy test for free at a clinic. Do it. You're scared and confused. Better to know, one way or the other (even if the news isn't what you want to hear), than to not know.
You're probably perfectly fine, but it will make a big difference in terms of how you sleep at night if you know for sure, one way or the other. So go and get tested, and get tested for HIV while you're at it. Now that you've become sexually active, that's a concern, condom or no condom, faithful boyfriend or no faithful boyfriend.
Best of luck to you.
