My doctor is going to start me on Progesterone tonight. The brand name was Promethazine, but we bought the generic of Progesterone because it was way cheaper. I know it's supposed to be taken vaginally, but I'm wondering about side effects, especially when it comes to tracking BBT and spotting. Will taking progesterone give me high BBT even if I'm not pregnant? And will it gives me pregnancy like symptoms even if I'm not pregnant? Any crazy mood swings?
