First time using Clomid

I got diagnosed with PCOS about 4 months ago and recently started taking Clomid (yesterday was day one) and I had unprotected sex yesterday. I’ve been trying to conceive for almost 9 months now and I don’t get my period at all. I’m just curious how soon you can get pregnant while taking Clomid and Metformin..? Really hoping to get my BFP as soon as possible!
