Im scared

I think i may be pregnant but im not sure. I was supposed to get my period 5 days ago, and ive gotten like all the usual period signs, cramps, acne, i currently have a uti so ive been peeing a lot, ive been pmsing like fuckin crazy, my moods are everywhere.

So the thing is, if i am, i am completely and utterly fucked. Im only 16, my sister got pregnant when she was 16 and so did my mom so im inder all this pressure to not fuck up and if i do thats just like the end of my life.

But the last few weeks have been especially stressful so im hoping and praying thats what it is before i have to be out here making really bad life choices
