Progesterone and clomid....

Ashley💄 • Me 33, SO 37 ttc#1 for both of us. Been trying to actively conceive for over 6+years. Diagnosed with pcos and Incompetent cervix. TAC placed in June 2018. FET #1 BFP due 10/2019.
So this is my first month on progesterone and clomid. I started the progesterone and I am supposed to take it for 12 days then on CD 3 I start clomid. But I am on day 8 and have started to spot. Should I stop taking progesterone and let AF start since its coming already or should I finish out the progesterone then start clomid?
