NEGATIVE 4 days before period 😪😪😪

I’ve done everything right. Taken supplements, good diet, drank so much water. Had a lot of sex all through the month so no way could’ve missed ovulation. Even tracked ovulation and temp. I don’t know what I’ve done wrong. I’m 21 and lost a baby at 21 weeks last year. Is there something wrong with me? I was told I’m healthy? Sorry to rant. I’m just so upset.

Im 10dpo. Is that still to early to test? I got a positive at 8dpo last time.
