Hi! I've been ttc for about 4 months. I have 1 child, and it was very easy to conceive. I had been on bc for many years, 3 months off and it worked. Now my cycle seems crazy. I will spot for up to 5 days prior to period, and for the past few months I've been starting 3 days earlier than the previous month. I'm still getting, at least I thought, positive ovulation tests. I'm afraid I'm going to have a very hard time conceiving due to my erratic cycle. Thoughts or advice? Thanks!
