I find my boobs swell and get sore after "o" to AF - though that is just my body.

I tend to look for other symptoms that I may get if preggers.

1. Metallic taste when I wake up (the taste you get when you need to brush your teeth straight away)

2. Nausea

3. Tired

4. Emotional

5. Nipples get bigger, darker and more veinier!
