spotting

This is my fort baby bean and I have had irregular cycles for over a year. I seriously doubted I could ever get pregnant. I have been spotting. Light pink only when I wipe. I'm 4w 2d and went to the OB yesterday and she said it appears I have bleeding on the outside of my cervix. I'm so scared. I'm waiting for my second hcg level and praying it has doubled. Please stick little bean!
