When to seek fertility help

D

What is the soonest you’ve sought a doctor’s help when TTC? What tests did doctor do? How did you bring up concerns to your doctor? I’ve read many posts that say 1 year if under age 35. I am 30, but I don’t want to wait a year. Our first was conceived after 1 month TTC. Now TTC 7 months. Haven’t felt quite right since stopping birth control. Up and down moods, cramping almost daily (even when not expecting AF), irregular periods (or months without a period), some months I ovulate and some I don’t. Any advice is greatly appreciated! Baby dust to all!
