I’m nervous about nausea!

I am 4w5d(ovulation confirmed by bbt). Due to a history of repeat 1st trimester miscarriages, and some bleeding 5 days ago, I’ve had serum hcg tests measured three times in the last 5 days. My serum hcg first quadrupled, then tripled, and I’ve had no further bleeding. I’m hoping and praying things continue progressing well. However, as of today, I’m undeniably nauseated. My animal feed smelled like manure this morning. I’m not even 5 full weeks. This is the earliest I’ve ever had unmistakable symptoms. I have two young children I’m homeschooling, goats, cows, chickens, ducks, a LGD, and cats all depending on me, while I’m tending the house, property, and doing an online school program I’m trying to finish. My husband works long hours, and we live in a rural area. I’m by myself.

I need your best recommendations for nausea management!
