It’s easy to give subcutaneous injections (under the skin on your belly) yourself. Intramuscular (IM) shots are harder to give yourself, especially progesterone in oil. Most IM shots are less painful given into the gluteus muscle in the upper outer part of either butt cheek, which is hard to do yourself. Some women do the shots themselves, looking in a mirror. Ask a Nurse or Medical Assistant to ‘mark the spot’ for you.
