I didn't believe in IB bleeding till I actually experienced it with my last (short) pregnancy. I lightly spotted 21 days into cycle and 7 days post ovulation. I unfortunately miscarried a few weeks later back in December. Now I started trying again and Im 21 days and 9 dpo with sore breast back ache and cramping and today I saw light pink blood. Usually I do spot about 11 dpo. I'm really thinking its IB, it looks like the same as last time. I'm sooo scared because I hoped I would not ever go through bleeding in a pregnancy again and if I am pregnant I will call my doctors that day.. Anyone else have the same experience?
