Earliest pregnancy symptom

Hi ladies, I have an almost 9 y/o daughter and currently ttc baby #2. This is officially our first month trying, it took us 5 months to conceive my daughter after being on birth control for so many years. I never got back on birth control once I had her but considering my age difference now I don’t know how long it could take this time around. I’m 2 dpo and have had really vivid dreams the past two nights and a lot of them. Is it too soon for that to be a symptom?? With my daughter I had no symptoms at all leading up to when I got my bfp. Thanks I’m advance!
