Nausea from estrogen?

Sa

I’ve been on estrogen so many times before for <a href="https://glowing.com/glow-fertility-program">IVF</a>/FET and from recovering from multiple surgical hysteroscopies, and I’ve never been nauseous before. Trying to figure out if this nausea is from the estrogen now or covid, which my other symptoms are starting to improve. Anyone been nauseous from estrogen? Or from covid?

Thanks
