Pregnancy symptoms?

I'm trying to conceive and yes I should really be happy that it's a strong possibility that I could be but lately I've been extremely moody and this morning I literally went from happy to sad to pissed off I'm afraid of telling my fiancé bc I kinda went off on him this morning and now he's not talking to me😢😢this hurts big time I have no one to turn to to talk to my emotions are all over the place Idk I really think I could be pregnant we had unprotected sex on the fifth which he did cum in me which was also the day after my cycle I'm due for it again on the 26th but I haven't had any premenstrual symptoms all I've had a massive increase in food craving STRICTLY dairy products I even ate eggs and I hate eggs my breast ache from time to time I'm always sleepy and moody I been smelling weird stuff that normally won't affect me but I smelled toilet water and instantly got queasy I wasn't even in the bathroom I was in the living room. Do you all think I'm pregnant?
