I’m I pregnant?

So...I had unprotected sex 9 days ago (yes he did ejaculate). And this morning I woke up to a light pink blood mixed with clear mucus. I also had this 2 days after sex. The first seven days after having sex I was having nausea (with vomiting), dizziness, fatigue, discharge (lots of it), my eyes are light sensitive, cramps, cramps and pelvic aches on one side (left side), etc. So I’m not sure if I’m pregnant or not, should I take a test? And do u guys have any advice?
