See Dr. before #2?

We're ready to start trying for #2. However, my hormones have been out of whack since #1 was born in July. My period wasn't starting again, even though I had stopped nursing in October. I started taking vitamins and supplements in Feb and finally got a period in March followed by a 41 day cycle. I'm hoping my body will continue to sort things out so we can start trying again but I'm wondering if I should see my doctor at this point for a preconception appt. Is it worth an appt to make sure we're good to go or do I wait it out? Thoughts?
