Pregnancy Symptoms or PMS?

I was pregnant for the first time in June of this year. We had a MMC in August and started TTC again in October. Now I’m 6DPO with AF (not) due 11/10 or 11/11. I know June wasn’t that long ago, but I cannot seem to remember my symptoms! Besides being extremely tired and cranky, the only symptom I seem to have is a dull cramp/tight feeling in my lower abdomen and lower back. This morning I noticed a lot of small bumps on my chest that aren’t normal for AF. It’s probably too early for many symptoms, but is anyone else experiencing this? I’m probably just going crazy because TWW is killing me. 😂
