This can’t be right? Please read

TTC this month, I’m sure I ovulated earlier than my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> told me because I was keeping an eye on my CM and I can tell my fertile CM. I’m roughly 9-10dpo. I took a test this morning and got a faint but definitely visible pink line. My question is, I’m feeling really nauseous today, I’ve been feeling nauseous every morning for about a week now but today it’s quiet bad, I’m most likely actually going to throw up. I’m thinking it must be related to the FP I got this morning but surely it shouldn’t be this horrible already at so early in my cycle? My AF isn’t due for another week. I have never in my life had sickness/nausea as a PMS symptom so I know it’s not that. Any comments will be greatly appreciated.
