Nausea?

ki

Can nausea start before you get a positive on a test? I've been nauseous on and off for like 2 weeks now, but I've gotten 2 BFN. My period isnt due for almost 2 more weeks. With my daughter I was never nauseous until a few months in, so I'm not sure. I also got a period with her the first month and found out I was pregnant like 2 weeks before my next period. 🤷‍♀️
