Is there something wrong?

Jenny • Hi! I`m Jenny. My husband and I are expecting twins in Dec. We have a 2 yo girl and are now adding 2 more girls to our family! I`m looking forward to using this community for support!
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!
