TTC #1 my concerns pls help!

sandy • Married for 4yrs ... to the best man in the world ❤️ Now waiting for my two little girls to arrive . 🤰👯 Love my life & the way my love has designed it for me 👫
Hi we are TTC our #1 since 6months .  
About me : I'm sandy ,29yrs . Height :5.3" and 170pounds (I knw I'm overweight) 
My story : I've seen my doc and she did a bloodwork  and a intravaginal sonogram and said I'm perfectly normal & that I can conceive naturally. I'm a hypothyroid since more than a decade now and on meds. Doc said my thyroid levels are normal too. 
About husband : he's normal weight . His semen analysis was done and today I got the results that everything was normal . 
Why am I not conceiving if everything looks normal ? 
My doctor wants to know if I want to try naturally or start with Clomid . 
Today is my day 1 period . She asked me to come on day 2-3. But I'm not sure what to do. Go with clomid or just try naturally?? 
I already feel devastated about not having kids for 4lonf years of marriage 😓 pls help. Thanks 
P.s : The pic is for distraction and he's my absolute stress buster ❤️🐾
