Nervous in case it's my mind playing tricks 😖

So AF is a day late & I've been feeling super nauseated...Today I threw up a little but two days ago I threw up a good bit...I tried eating today but it made me want to be sick..I feel exhausted & have been having some tummy cramps & a headache...DF wants me to do a test in the morning but I'm wayy to nervous in case it's a BFN & my mind had been playing cruel tricks..Have been TTC 8 months & just don't think I could handle a negative this time round 😔
