Am I sneezing because decreased immune system is a symptom of early pregnancy OR because I did turn the heat up high enough last night? I didn’t feel cold. Idk 🤷🏾‍♀️

I know one thing, my poor husband did not sleep well at all because I woke myself out of sleep with a fit of sneezes and sniffles all night long into the morning. Could not wear my perfume and I’m trying to have a coffee flavored drink but the smell of “coffee” is also irritating my sinus.
