13 DPO

When should I test ??? My cycles usually range from 38 to 40 days. I've been taking prescribed progesterone pills by my doctor (3rd month now.) Taken as directed after ovulation(CD 15), start on CD 25 for 12 days. This past month I've started to work out and gain healthy eating habits. My mood has been calm and I've been cleaning a lot, taste buds were out of wack all day yesterday. Is it too early to test ?
