Nausea before period/BFP?


Hey guys, just wanted to see if there was anyone who ended up with a bfp who experienced some nausea beforehand. I had some severe nausea (almost vomited) 11dpo. The nausea went away pretty quickly after I spit out probably a bucket full of saliva in the toilet (sorry for the visual) and it hasn’t come back since. I have tested on 13 and 14dpo both with negative results. My AF is due in a day or two. I just never experienced this before and I know I should just be patient and wait, but I’m just so desperate now. We’ve been trying for almost 2 yrs. Thanks for your help.
