Light pink when I wipe ?

Mariah

Okay so I am on the shot , I've been on it for about 2 months now & never have I bled but today this morning I went pee & wiped & seen a very light pink color but wiped again & nothing then just about 20 minutes ago I went pee again & seen the same thing . Does this have anything to do with the birth control or does anyone know what it could be ?

Also these last 2 days (not today tho) I've been feeling like throwing up & the first day I couldn't even eat 😣
