5 weeks and loss of symptoms and BBT drop

I’m 5 weeks today. For the past week my symptoms have included mild cramping, tender sensitive breasts, and heightened smell. My bbt has ranged from 98.2-98.56. This morning my bbt dropped to 98.0 which is a 0.20 decline, and my symptoms have seemed to vanish. No cramping, breasts are far less sensitive and tender, Yesterday my sense of smell was not nearly as sensitive. I know it’s normal for symptoms to come and go, but this is my second pregnancy and my first ended in miscarriage at week 5 so I’m a little paranoid. I’ve put off telling my husband because I’m so afraid of miscarrying again. Any assurance would be greatly appreciated. Haven’t had a chance to schedule a Dr. apt to check my HCg levels yet.
