Could I have a Spigelian Hernia?

I am 7 months postpartum and the pregnancy really messed up my abdominal wall. I had a big 4cm gap after the pregnancy and then had an umbilical hernia which had since been repaired. After the birth I had this severe pain on my left side in-between my hip and belly button. I could feel a slight bulge. The pain was so sharp especially when I would walk. It eventually subsided after 3 months and my doctor didn't seem worried. Now it's started to hurt again and the bulge is a bit more noticeable. I get either a sharp pain or a dull ache. It's not un bearable, but it's annoying and causing me anxiety. I have added a Pic of the bulge ( was really hard to get a picture because it's not so visible in photos) and i have uploaded a photo where I circled the area of the small bulge and pain. The bulge is soft and not hard so also hard to feel.
