Dating but ready for children.

I am currently seeing a guy and though we haven’t been together for a long time, but we are both ready for a baby. We talk about it sometimes and we’re not doing anything to prevent pregnancy... if anything we’re doing everything to make it happen lol so lately he has been ya know releasing his sperm into my body and I’ve been ok with it. Well lately I’ve been nauseas a little, my sex drive is through the roofs and I’ve had constant headaches and body aches.. Are those early signs of pregnancy? I also have Lyme disease so the body aches are somewhat normal, everything else is not.
