Positive ANA and thyroid

I am currently undergoing IVF for PCOS, an ovulation. My first cycle I collected 26 eggs, 24 of which were mature and all fertilised and ended up with 12 day 5 blastocysts only 1 of low quality.
First FET resulted in chemical pregnancy and 2nd resulted in negative result. I have had all blood tests done and only thing that has been flagged is a spot I’ve ANA result at 1.80 titre with a speckled pattern. Also struggled to get my thyroid TSH to an optimal level ranged from 1.7 to 3.8. T4 and T3 always normal and no antibodies.
Should I be doing anything different for next transfer or any further investigations?
