Advice?

Sooo my boyfriend and I had sex a few weeks ago and he didn’t pull out like normal and now I’m spotting.

I’ve never spotted in my life. I looked it up and multiple websites said that was a sign of early pregnancy.

Should I be worried?

I don’t wanna just brush it off.

I’m supposed to have it in a week or so.

I’ve also been sleeping more and peeing a lot more and sometimes I feel like I’m gonna fall over even if I have my balance. I also don’t feel the need to eat as much anymore and have been getting a lot of headaches.
