Help could I be pregnant!?!?

I had my 3rd baby a year ago jan 5th and got my 1st period right around that time this year! I haven’t had a second (it’s been 13 days) and I know they can be super irregular but I have felt so incredibly weird the past week nauseous and so tired!!! Yesterday I woke up and all food tastes funny!! I feel like I can taste it in my nose!! It’s awful!!! I don’t want to eat anything because of it the after tastes are lasting forever! And my scents have definitely heightened!!! My husband said our 3rd was out last I would want 1 more but I’m not ready to have another now and we definitely do honor have the room for another right now!!! What do you all think?
