Is there anyone else experience nausea through the day, headaches, fatigue, and extreme bloating during the the time of getting VVFL?

My cycles are not very predictable so I am not sure how many DPO I am. But I expect to be starting a period between today and a few days from now, if it is to come at all. I just never experienced nausea before a period like this and I have been testing since yesterday with vvfl’s but I am still unsure if those lines mean positive.

Any thoughts?
