Don't know what to expect!!😞

Ugghh is it normal for some days to be worse than others?? I feel fine, then I don't, then I feel fine again. I am 5 weeks 4 days and I haven't been spotting for awhile and all of a sudden today I wiped quite an ammount of reddish, brownish discharge. Someday's my stomach hurts, someday's I get cramps, someday's I'm gassy, someday's I feel bloated, someday's I'm hungry and other days I'm not..is this all normal??
