Is it all in my head?? 😥

The first day of my last period was dec 23rd and after my period i stopped taking my BC pill & had unprotected sex before, after, & during my ovulation. I’ve been feeling a little weird and tired but i just don’t think I’m pregnant yet sadly but my boyfriend thinks i am and my mom and his mom has been mentioning baby stuff and he had a dream about it but i don’t want to get my hopes up.🙄 I have. Obgyn appointment on Monday but i took a test like almost 2 weeks ago and it was negative 🙁..Any advice?
