Pregnant ? 😳‼️

I havent taken a pregnancy test as of yet but i have been feeling more odd than usual . Im use to being nauseous everyday , hungry alot but i thought the hunger was because i smoke , I usually use the bathroom about 5 times a day & I havent had diarrhea in YEARS . Ive Had unprotected sex because im trying to conceive. I feel nauseous all the time now before and after i eat , some times I be sooooo bloated I get scared . Im hungry almost every hour . I use the bathroom now about 20 times a day or more & i had diarrhea!  I have fatigue and headaches as well . My period came and gone in the beginning of march . Is it possible I might be pregnant ?
