Aw mama, totally understandable na natatakot ka, lalo na first time mo, pero good thing na aware ang OB mo at nag-refer na sa Endo agad, so you're in good hands! A few of my friends have had thyroid concerns during pregnancy din, at honestly once properly managed with the right treatment if kailangan, ang babies nila turned out perfectly fine, so try not to worry too much. The fact na normal pa ang FT3 & FT4 mo is actually a good sign, kaya definitely go to that Endo consult next week and ask all your questions there, they'll give you the clearest picture based sa exact numbers mo. You're doing everything right, mama, and catching it early is the best thing na magagawa mo.
