HELP IM NEW TO THIS AND WEVE BEEN TRYING FOR ALMSOT A YEAR NOW .

My period is 5 days late , i have slight cramps through out the day but they aren’t period cramps it’s kind of like a poke or something in my lower stomach area & I’ll have cramps in my vagina (if that makes since), I’ve been nauseous for the past week & a half mainly in the AM but sometimes through out the day too, I randomly started craving fish ( I hate fish, the smell of it makes me sick) , I have lower back ache, & some what frustrated with things & super tired , & I’ve noticed white discharge in my underwear . I haven’t noticed anything else . Is it to early to tell if I could be pregnant ? I’ve taken tests & they’re negative ☹️
