I've been on petogen since July 2012. i stopped having periods. my  shot expired on 27th Nov i ws due for the next one but i went to have one on the 1st of Oct and in the morning before i went  for a shot i had unprotected sex.

I hear they say this form of birth control is very strong, and that am safe.

I got flew and i was coughing about a wk and i was vomitting as well. Now last night i started feeling cramps as if am having periods so this morning i saw so brown yeast. the cramps are there and its itchy when i urinate and my urine is strong(yellowish).

Could this be a bloor infections or pregnancy?
