9dpo... Pregnancy symptoms or PMS?

So I’m just trying to figure out if these things I’m feeling are early pregnancy symptoms, or PMS.

1. I’ve had heartburn the past two days, which is not something that’s normal for me!

2. Earlier today I felt nauseated until I ate something and then it went away.

3. Right now I’m in bed with nausea (I already ate, so it’s not from hunger) and stomach pain, feeling constipated too (sorry tmi!)... of course it could all be from something I ate but because of the timing I am possibly “symptom spotting” as they say!

4. I had an intense craving for chocolate which I usually do during PMS, but can this happen for pregnancy too? Also, once I ate the chocolate, it tasted funny, wasn’t necessarily satisfying like it typically is.

5. The last few days my nipples have been very sore (never happens to me during PMS) and today it’s more just sore boobs and they’re bigger/heavier (that DOES happen to me during PMS).

6. I am also SOOO tired! At one point I just had to close my eyes and nod off, even as I was watching this show on Netflix that I’m completely hooked on! (Bridgerton, any of you ladies love this show too?!)

I took a test this morning and it was BFN although I swear I saw the faintest of faint possibly imaginary line that did not show up on camera, so it could very well have been “line eyes”.

Anyway, I guess my question is, do any of these sound like potential early pregnancy symptoms? Is it even possible to have symptoms before your BFP?

Thank you ladies💓
