Pulled muscle

Has anyone ever felt what feels like you have done son stretches in your lower stomach around your uterus after ovulation? And did you end up becoming pregnant? Okay so here is my thing my fiancé and I BD every day for the past 5 days which was all my fertile days sep for we didn't BD the last or first day. I know I ovulated the 17 maybe sooner. Since yesterday I have felt like I have what feels like lightly pulled muscles (nothing painful) in my stomach like right around my uterus. It's been off and on and then some twings or light cramps on my right side here and there. Do you think I just pulled a muscle or is something happening or do you think it's just part ovulation? I've never had this pulled muscle feeling. It's all new to me and I can't go off pregnancy symptoms cause sometimes I have those when my period is close. Anyways what's your guys opinions?
