low progesterone

a little worried my progesterone is too low 😞 these were taken when i was 5w1d i am now 6w1d & i let my dr know i was worried abt low progesterone. he told me he doesn’t believe in progesterone tablets or anything else actually helping a pregnancy (i have pcos & thought id ask) since my last visit i’ve developed more spotting, i’ve had two previous miscarriages and i’m worried sick. what do you guys think
