Timing of Pregnancy

Tia
My husband and I just started trying to get pregnant this month, so it isn't shocking that it didn't happen the first month. (Though, it would have been great if I did!) I'm almost 27 and he just turned 30, we've been married for 2 years and together for 7, so we're ready for this next big adventure in life. My question is how long did it take you to get pregnant? Were you trying or did you get an unexpected surprise? Is your baby a rainbow baby? I just want insight from mommies because I don't have many friends to ask these questions to. Is there any advice or stuff to steer clear from? I do have an under active thyroid, so I know this could make it more tricky!! 
Thanks in advance, yall!! 😘
