Almost 4 weeks pregnant! Need advice!

Amber • 21 Y.O. / Married/TTC baby #2
This is my second baby. Near my left ovary, when I press on that area it feels SLIGHTLY stiff. And when I press on it, it almost tickles but not really. No pain at all. Just wondering if the stiffness is normal? Its not like that on the other side. I don't remember if I felt this or not with my first child.
