Help! My allergies are sooooo bad. I usually take a Zertec every night before bed. I found out I'm pregnant after 2 failed rounds of <a href="https://glowing.com/glow-fertility-program">IVF</a> and over 2 years trying. I'm just thrilled. I'm 5 weeks exactly today. I'm really looking for some relief as I'm sneezing constantly. I have Flonase. Can I use that as well?
