On Depo Shot. Had Protected Sex. Started Spotting. Should I Be Worried For Pregnancy?
Thanks for writing in to us.
The typical use of male condoms, which is the average way most people use them, has a failure rate of 14-15%. Hence, even with condoms, a possibility of pregnancy DOES exist.
Also, after the Depo Shot, it is very common to have irregular and erratic bleeding,alongwith total absence of periods or haphazard light spotting sometimes.
It is extremely difficult to distinguish between early pregnancy or the hormonal effects of Depo in your case.
A home pregnancy test kit also is 97 % effective, but to be 100 % sure, I would suggest a proper check up by a gynecologist which would include a pelvic examination and an ultrasound / blood tests if any doubt exists.
Meanwhile, to increase efficacy rate of contraception, you might try combining condoms with some other method, like the pill, which is known as a " dual " method.
Take care and feel free to ask for further clarifications.
