Aww pear I love it when I make friends in the most unexpected locations. I am friends with my dental hygienist and she has two boys the same ages as mine. Hope you are able get together outside of your physio treatments!
With #1, first symptoms were extremely sore boobs, weird cramping that was way before my period was due and never happens for me, and just a metallic taste in my mouth. I never in a million years thought I was pregnant so those symptoms threw me for a loop! Took a test and immediate BFP. Turns out I was already 7 weeks!
#2 I found out I was pg just because I was at a doc's appointment! I had no idea, so I had to have a scan that showed bub at 5 weeks with a fetal pole and then another one at 7 weeks that showed an actual heartbeat. Symptoms were really, really mild. Little to no morning sickness, just really, really tired. So I didn't really get to symptom watch with him.
#3, I just knew. Sore boobs right away. I don't normally have that as a period symptom, so I just knew based on that. Took at test at 11 dpo and it was a faint positive. Tested again a couple of days later and it was darker! Horrendous morning sickness with her compared to what I dealt with before. All day nausea and extreme tiredness I remember being the hardest... but I don't think they started up until around 6-7 weeks.
