Could I pregnant at 10 dpo?

I am 10 dpo after having an IUI. My hubby's count was very good and so were my follies. For the past couple days I've had sore bbs ( are always inverted and they're occasionally popping out..tmi..sorry), constipation, very tired, vivid dreams. We finally got preggo after two years and miscarried two months ago at 4 weeks. I had these same symptoms minus constipation. Just don't know if my body is playing tricks on me, its really happening or I'm just crazy! I've been testing w/ an extremely sens test and nothing yet. Any thoughts??
