Hcg vs normal progesterone levels

Hello,

I'm about 9 or 10 dpo. I tested early yesterday night (i know, in know - too early) and saw a vvfl. I tested again this morning and bfn. Ok. I know it's early so who knows. But today I'm getting some weird symptoms. Like I almost fainted in a meeting - i have never EVER felt like that before. Came out of the blue as I was just sitting there and talking. I drank some water and ate so i feel a bit better but weird right? I also have mildly sore breasts, super tired, and some nausea on and off but I know this can just be pms symptoms as well.

My question is this - let's just say i am pregnant but i would obviously have a very low amount of hcg in my body. Is it normal to have symptoms like dizziness right away? Or is this just some weird pms symptom. I've never even heard of being dizzy in pms...or at least I never have.

I know i have to ride it out ans wait. Just wondering if anyone else has experienced this or had a vvfp and then bfn the day after (so early on).

Thanks!
