I'm pregnant! Maybe not, what do you think?

I took clomid on cycle day 5-9 (September 28- October 2) My hubby and I BD on cycle days 12, 14, 15 and 16( between !0/05- 10/10). Don't know what day I ovulated but I know I did because on cycle day 22 I had my progesterone levels done and they were 11.4. But beginning on cycle day 16 I have been bloated and feeling discomfort in my lower abdominal, but that could be from the metformin I have to take everyday, I don't know. Starting on cycle day 23(10/16) my have been getting sore and today the little bump you get on your face when your period is about start showed up. Is this to early, because my period isn't due til next Saturday(10/24)? If this were you when would you take a test? Or would you just say this is my period getting ready to start and just forget about it? I know you all are going to say take a test, but when should I take it? And can I use a test from dollar tree before my miss period?
