I'd talk to your OB immediately & explain everything to him & see what/how he wants to handle it. (You may also have to fudge a bit & tell your OB that you have been TTC a year - typically they don't want to get involved unless you have been trying a while.) I wouldn't necessarily ask for clomid if you don't need it - something else may be going on, IDK. I'd also make sure you get routine fertility bloodwork done (including the thyroid test).
I actually started trying about 3 years ago. My OB never did any bloodwork on me but skipped straight to the HSG (he said that typically the bloodwork comes back normal). I then found out about the bloodwork & specifically requested it & found out I'm hypo. I had to get that fixed before even thinking about clomid - which I did & then learned that I had a progesterone deficiency as well, which the clomid was used to help. The first cycle of clomid, my progesterone was great but the 2nd cycle my progesterone was extremely low.
