I had a bit of spotting which disappeared after a day and AF never came. That made me think I might be pregnant so I tested. In hindsight I was really hungry the second half of that week before my BFP, but I would never have realised that might be a symptom. Apart from the hunger which lasted until 7/8 weeks, I was 5/6 weeks before any other symptoms and 7 before my boobs started to change. x
