A few days before a BFP, I started having very vivid dreams (most of them were horrible). The night before I peed on a stick, I dreamt about having a positive test. That happened in my last pregnancy, too.
I also started noticing that I was FREEZING, all the time. Even though we were keeping the house about 5˚F warmer than normal, I was shivering and wrapped up in a blanket all the time. I didn't feel sick in any other way, so I Googled "Is being really cold a symptom of pregnancy?" Turns out, it can be.
Had the positive test dream that night, got a BFP next morning.
Other symptoms for me were PMS symptoms. My PMS symptoms are identical to pregnancy ones. Nausea, sleepiness, sore nipples, light cramping, some cravings, etc. They're so similar for me, actually, that I thought I was just finally getting AF (first one after a miscarriage), and the only reason I tested was because Google said being cold could be a symptom of pregnancy, but its not a symptom of PMS.
Shortly following the BFP, I bloated. The exhaustion didn't get too bad for a few more days. I mostly just felt a little worn out, like I needed to eat or something. But then the full-on exhaustion hit, at around 6 weeks. The nausea was also very light... mostly in the evenings, having a can of Ginger Ale would make it go away completely.
