Hopefully this helps

Hey ladies. I just got my BFP this Sunday. I kinda knew because I kept crying over EVERYTHING, my back was hurting, I would get hot flashes, I would crace something but once I finally got it I wouldn't eat it, my nose became so sensitive to smells, I started having lots of saliva and ny nails had grown out a lot. Weird I know, then what made me test was I went to the grocery store to pick up am few things, smelled something weird and had to take off running to their restroom to vomit. Every woman is different but ur body will definitely let u know for sure when something is strange. hope this helps, good luck ladies.
