So unsure

So I took clomid at the start of my cycle this month. I guess it was really early this month or late last month. We BDed right before my fertile window would be. Now I've had pressure in my lower abdomen, am crazy tired, my boobs hurt to put on/take off a bra, and I've had a headache for a few days. Anyone have similar symptoms in early pregnancy? I'm afraid to take a test and have a BFN. I just really hope this is it. I never have these kind of symptoms with AF
