Heavy/Aching Uterus?!

Kimberly • Pregnant with our first baby!
I'm about 5 DPO and TTC. I am feeling a very heavy aching feeling in my uterus. It's not terribly painful, but I always can sense my uterus and when I do it aches. We are TTC so I could be psyching myself into something but it's bothering me. What do you think it is?
