So I think I might be pregnant but I'm not sure.

Last month I was dating a guy and unfortunately it didn't work,but we had sex a couple times before breaking it off.We only had unprotected sex cause I'm a dumbass,he pulled out tho,but I know this doesn't always work.

We had sex las time on the day of my ovulation.My period came only two days late which is pretty normal for me,but now I am struck with a lot of pregnancy symptoms and this has never happened before.

I have bad nausea throughout the day,mostly in the morning 'til around 11.

I am severely constipated and a little bloated.

I had some light cramps today.

My CM is a different consistency than it usually is at this point in the cycle and in a different quantity.

And I had some light dizziness.

Forgot to add the first time that I also experience some light to moderate acne,fatigue,peeing more often and a higher sensibility to smells(if I feel a bad smell I'm almost puking in like 3 seconds)

I know the chances are slim because my period already came,but I heard stories of women getting their periods as normal and then immediately being hit with pregnancy symptoms and finding out they are pregnant and it actually happened to my biological mother with her first pregnancy.

Could I be pregnant?I'm just turning 16 and I am extremely scared cause I'm only a freshmen in highschool(not from America,school system is different).
