Exhausted

I'm so exhausted between work, trying to eat low carb (for weight loss and PCOS) TTC and not getting any results. I have an appointment in December with an ER and I'm so upset I couldn't get pregnant with help from the regular OB 😢😢😢 my cycles are back to normal thank you lord! They evened out after I lost an initial 50 lbs. Now I need to lose another 30! That's mainly my goal before I get to the ER just to show how much work I am actually putting in towards helping my chances. Another 30 pounds would do me good anyway because being overweight isn't good for anyone but I would have another 100 to lose after that (I would be 245 after the 30 lost)! I need some encouragement, BFP after TTC with PCOS, with help from an ER, just any positive TTC with PCOS. Thanks y'all
