Pregnancy Symptoms

Kirstin
For those of you who have conceived already: what were your earliest pregnancy signs and when did they kick in? With #1 I didn't have any symptoms until exactly 6 weeks. I haven't gotten a BFP yet, and honestly I only ovulated like 5 days ago lol. But my boobs are SOOOOOO  heavy and are killing me. I'm trying to figure out if it's just an impending visit from AF or if it could potentially be an early pregnancy symptom. Thanks!
