Scared to test

So my period was due today and it didn't show. A couple days back I checked my CM and it was sticky pink tinged cm it was like that for 3 days and then it stopped but it was only when I checked my CM. My right boob feels full and bigger compared to my left one. My nipples are itchy and sensitive. I've also experience cramps and cramps in the middle of my stomach. My last period was from april 14 - 18 and I had sex on april 30th, may 5 and may 7. Today is may 18 and I was supposed to start. Any opinions? I'm so anxious but don't wnana get my hopes up 😩
