Pressure on lower abdomon

Well to cut to the chase. I have this pressure on my lower stomach like hurts when I get up from sitting or laying down. And hurts when sitting forward when driving. My mother thinks I'm pregnant, but last time my body did this it was just a cyst that went away on a few days..btw my husband had ejaculated in me on the 17th (according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> is my fertial week) so idk
