Changing in taste preferences

Jill • Spent a year trying to conceive. Finally prego w #2 @ age 35. Due Apr 4.
Tonight I asked for my little grilled BBQ pizzas without jalapeños or garlic and my partner just about hit the floor.  Garlic is a food group in our home, jalapeños is like the next food group...every possible thing we eat has jalapeños and garlic.  But the taste and smell are kind of grossing me out.  Anyone do a complete 180 on taste preference?
