Start of something? I’m so confused

Amanda

I have been nauseous and throwing up the past 4 days with a really bad headache and pure exhaustion. I haven’t felt like this since I was pregnant and so I took a test but it wasn’t one of the early ones. I just got done breastfeeding a couple weeks ago so my period has been out of wack. I don’t know what day I would be on. Is this a very faint line or start of something? I plan to get another test today.
