Vomiting but negative test?

Kristin

We are TTC and attempted on 2/25 which was my ovulation date according to my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> for the last week I have been having night sweats and dizziness and night sweats was something I had with my son (6) early on and was one of the first symptoms I noticed I woke up on 3/8 fed the dogs and the smell of the dog food triggered vomiting i felt perfectly fine after went on to have my coffee and breakfast and feeling completely fine I even ended up going to work because I had no temp and felt normal by 2pm I vomited at work and went home but no fever no other symptoms except my night sweats and dizziness. 3/9 I woke up got in the shower and vomited then too but still otherwise felt fine just super tired my DH spent the day with the kiddo and let me sleep I woke up and took a dollar tree test and it was negative? I woke up this morning still kinda dizzy but mostly feeling fine and took another dollar tree test first thing this morning and it was also negative I haven't been sick this morning at all and feel a little dizzy and I'm due to start my period tomorrow so I guess I wanna know has this happened to anyone else and they still ended up being pregnant?
