Please check my TSH LEVELS. About it?

Dear Sir/Mam, I have done my thyriod panel test done thrice in last 4 Months. Please check the three levels below:-           10 Feb.            2 April.          23 June T3-.   87.7 ng/dL-.   0.79 ng/ml ---0.8 ng/mL T4.    7.9.   µU/mL-. 5.06 µg/dl-----8.15 ug/dl TSH- 0.35 mIU/L-. 0.28 (µIU/mL)-. 4.65 uIU/mL Though my T4 n T3 are normal all through but my TSH earlier on 10 feb(0.35) n 2 April (0.28) was supressed and the Endocrinologist told me to take good diet as i usually did lot of dieting. I started eating good and when today i did my TSH again it raised to 4.65 uIU/ml Is it Normal that it raised from 0.28 on 2 April to 4.65 in today's report attached herewith? Is it is normal or possible? Plus i also did the Ultrasound Thyriod as advised by my endocrinologist. The scan was normal. I have attached the image herewith. Please advise me is there something abnormal why my TSH raised so much from the supressed levels of 0.35 n 0.28 to 4.65 May i need to do something about it?
