Could I be pregnant?

D.

Okay so on Tuesday 09/25/19 I had unprotected sex and now it's the 1st and my boobs hurt, I've been having light cramps in my back all week! I'm constantly hungry! Like I just want to eat everything! And I'm having dull lingering headaches. I don't know if I'm pregnant or not but I mean some of those are some of the symptoms. But it can also be symptoms of me ovulating because I still have 3 days left in my fertile window. And then I have about 5 days until my periods starts but I want to take a pregnancy teat but my boyfriend told me to wait to see my periods starts. But I'm so scared he wants a baby but I don't think we both are ready for a baby yet. I'm 23 and he's 24 and he's sooo ready to have a kid. But I'm scared, I'm not saying I dont want to havekids but I can't afford a kid. Someone please tell me what should do.
