I also had no symptoms prior to my BFP, and the lack of symptoms continued into my pregnancy. I had no morning sickness, no sore boobs and I had to keep looking at my HPT to believe I was pregnant. And then I fell naturally when bub was 8 months old and I just knew 2 days before AF was due that something was going on. This pregnancy has seen every symptom under the sun. So moral to the story, you just never know!!!
