Symptoms... or lack thereof...

Lauren
Hi ladies - I'm currently 5 weeks 4 days. And since I've gotten my BFP last week my only symptoms were a little bloat and really tender nipples. Now today, I'm noticing my nipples don't really hurt anymore. 
Is it normal to have practically ZERO symptoms? 
I'm kind of freaking out because right before I miscarried in September, my sore boobs stopped hurting. 
I hope this is not a bad omen of things to come 😔
