2nd Time Moms - advice please!

Did you notice pregnancy symptoms sooner with your second child? I am in the TWW and feel like I am going crazy.

2dpo: heart palpitations, anxiety

3dpo: mild, intermittent cramping both sides; heart palpitations, anxiety

4dpo: mild twinges left side; fatigue; car sickness (very unusual, except that it was one of my first pregnancy symptoms with my son); anxiety

5dpo; low, dull ache as if I am on day 3 of recovery from intense abs workout; couple twinges on the right side; exhausted; anxiety

I think I might be pregnant but it’s too early to tell. I am not trying to symptom spot but my next pregnancy will be HR and requires a lot of monitoring.
