Abdominal muscle pain

I’m 3 weeks pp and my abs feel so sore and painful! I didn’t start noticing it until about 1.5-2 weeks pp. It seems to be getting worse every day. Hurts to laugh, cough, anything that puts any amount of strain on them. I’m supposed to be cleared to go back to work in 3 weeks and worry that I’m still going to have this issue. I have a physically demanding job (EMT), and have to pass a physical fitness test that includes weight lifting before going back to work. Anyone else experience this? Did it get better on its own with time?
