Could I be pregnant

Yup
Okay so my period is about 4 days late now I did go to the beach last week so traveling could cause a delay. However, I usually have  pretty dry cm  around the time of my period or sticky kind. So I kept of feeling like I started and leaking all day. I went to the bathroom and I have egg white cervical mucus... I have slight cramping, slight nausea depending on what I eat, increased appetite  and I have been really sleepy. But all of these symptoms also can show up with a period. I haven't taken a pregnancy test because I didn't really consider it until now. I would rather not go out and buy one of I am just overreacting so advice please. Thanks 😊
