I am expecting Af in 3 days and usually I don't have symptoms until the day before it starts.. But ever since yesterday I've had light cramping around my pelvis and mostly towards my lower back. My ribs have been sore too for some odd reason. My breasts are hard an somewhat sore and two mornings  now I started getting nauseous and dizzy and dry heaving.. We've been TTC  hoping this is finally it! It's just so nerve racking bc I don't know if I'm just being paranoid bc I want one so bad or what ? I've been taking prenatals but I've also been noticing I don't get "sick" til after I take it..
