I had a miscarriage back in August. My fiance and I have been TTC since. Right after my miscarriage my cycle went right back to normal and AF is always on time. I am now 3 days late, my breasts are so tender, have horrible nausea and headaches. BUT I tested yesterday and it was negative. Still no sign of AF coming. Do you guys think it's possible that it was just too early yet or should I just give up on hoping this was my month? :/
