Hi, My Names Jacinta, 18 Turning 19 And Don't Know

Hi, my names Jacinta, 18 turning 19 and don't know very much and am a little concerned with a few things. A month ago my partner and I had sex and had an 'oops' moment (he cum inside me) and I took the morning after pill the next day. I had spotting for two days after taking it, then it slowly turned into what seemed like a normal period for about a week and a half almost two. Unfortunately my partner and I had another 'oops' moment about two weeks ago and for the past week I've been spotting like pink red colour on and off and then it stopped. As of two days ago I started spotting again with small red gel like clots and cramps but not as bad as my normal period cramps. Then it gradually got heavy as of last night, I woke up with red blood in my undies but as the days gone on the cramps are gone, and it's going back to being light and the colour is changing back to a light pink red colour again? I'm stressed out and worried, I don't know what's going on with my body? Am I pregnant, I need help.
