Progesterone preparations

Vaginal capsules or gel are the most common in Canada; intramuscular progesterone in oil is used in some protocols. Vaginal forms often cause discharge, and injections can cause soreness at the site. Use the form and schedule your clinic prescribed, and do not stop without speaking to them.
