Different early pregnancy symptoms for different pregnancies?

[cbeans]

Hi! I posted this in the tww, but it's more appropriate here because we weren't completely trying again. I was wondering if any of you had different early symptoms for your different pregnancies? My DS is 4 and my DD is 2. For both pregnancies the only symptom I had in the tww was fatigue and some vivid dreams. I am currently 8 dpo and have been experiencing mild cramping and low backache since 5 dpo (my normal af symptoms) and wondered if that meant I was out for this cycle - since my other pregnancies didn't have really any symptoms this early on. So, anyone out there have different early tww symptoms for their different pregnancies? Thanks!
