Okay, so I had the depo injection 2 weeks ago today and was advised to use condoms because I wasn t on my period but the Wednesday after, the condom split . So about 13 hours after I took the morning after pill (the doctor said it would be 95% effective because it was within the first twenty four hours) and since the Friday after the unprotected sex, I ve had this weird pain when urinating, like a UTI. It s now nearly 2 weeks after the unprotected sex and I m worried that I Could be pregnant or have an STI. A friend says it could be due to the mass of hormones I took in such a short period of time but I don t want to be 17 & pregnant.

Hello, and I hope I can help you today.First, the Depo-Provera injection becomes immediately effective against pregnancy the day you get the shot. The reason why it is recommended for you to start taking Demo while you have your period is to make sure that you have not already become pregnant and get the injection while pregnant. So if you had a shot two weeks ago, even if you had a condom accident, and especially since you took morning-after pill, there is no reason to suspect that you are risk for pregnancy. However, a urinary tract infection, which is inflammation of the bladder, can occur after sex if chafing during sex especially externally rubs bacteria into the urethra (the urinary opening).  This is common in women who use condoms as the ring on the condom can irritate this area during penetration. So I think you can be reassured that your symptoms are not due to pregnancy. However, I think you most likely do have a UTI and should visit your local physician or clinic for evaluation, so you can get a prescription for antibiotics to treat it.  If you are now going to be having unprotected sex with your current partner, you both should be tested for STDs to make sure that you are not at risk of giving anything to one another.  However, this point there is no evidence that your symptoms could be caused by an STD. I hope that I was able to adequately answer your question today, and that my advice was helpful. Best wishes,
