I am a 25 yr old female with 2 children. Over the last several weeks I have been spotting and noticed a disgusting smell since it started. Please help?

Get checked. I don't know the circumstances surrounding this or your sexual practices, but it is important to get checked out for the source of your symptoms which may suggest some type of infection, but also could be several other things.
Vaginal discharge. You really need to "open your wallet" and see you gyn for an exam.
