I have no one else to talk to. Please help.

I know I know that a penis has to enter the vagina for me to get pregnant.

But I had protective sex last month and had a full period after that. ( with a condom)

But this month of July. My boyfriend and I have been messing around. We haven’t had sex but his penis has been very close to my vagina and has even touched it. Precum. Because he would finger me right after that.

My last period came but it was only 3 days and it was heavy in the morning then light in the night. Which I usually don’t have. I have felt nauseous almost everyday and i has sore boobs before my period and now they are gone. And now my stomach is all rumbling and bubbles.

Is this just my head talking? Is my body tricking me because I am so stressed out about it.

I have been worrying about this for a while so maybe it made me last period only 3 days Cuase I was to stressed about it ?

I am debating on going to the store and getting a pregnancy test. But I know I am not pregnant. It’s not possible. I didn’t have sex this month.

Shoot. Guys. I need advice. Do I need to go get one.

Ps they are so expensive
