Freaking out! Four days late ?! Test?

Should I test Saturday morning or wait longer I’m super scared to test ... it’s my second cycle of the pill so I could be late bc my body’s trying to regulate? Had a period on Christmas than a second period on feb 16 barely like two weeks apart so . What do you guys think ? My boobs hurt like heck and I don’t feel like eating at all which is super weird for me Bc I’m always hungry .. but that I guess could be from my body regulating ?? It def doesn’t feel like AF is going to show at all
