Hi Katerina,
I'm assuming that you are not on any thyroid medication and haven't been (if you are, though, the free T4 and free T3 are the only reliable tests). It is not unusual for the TSH to rise before there is a decrease in T4 or T3. So it may be just a matter of time before the Free T4 drops. Your TSH number is somewhat high, indicating that your pituitary gland is working overtime to stimulate your thyroid to produce hormone.
Some other possibilities:
Did you get a Free T3 test? If that is low, is may indicate that you are one of the "poor converters", meaning the T4 that your thyroid produces isn't converting to T3 sufficiently (most of the T3 in our bodies is made from T4). If that is the case, your thyroid may be upping its production of T4 a bit to try to keep up, and your pituitary is getting signals from the low T3 that you need more thyroid hormone.
You may have thyroid hormone resistance (this is sort of like insulin resistance), in which your thyroid is producing sufficient hormone but your cells aren't responding to the hormone effectively. Do a google search for thyroid hormone resistance for more info about this.
Here is another possibility (a blurb from a site I'll paste the link to):
Thyroid Binding Globulin. Most of the thyroid hormones in the blood are attached to a protein called thyroid binding globulin (TBG). If there is an excess or deficiency of this protein it alters the T4 or T3 measurement but does not affect the action of the hormone. If a patient appears to have normal thyroid function, but an unexplained high or low T4, or T3, it may be due to an increase or decrease of TBG. Direct measurement of TBG can be done and will explain the abnormal value. Excess TBG or low levels of TBG are found in some families as an hereditary trait. It causes no problem except falsely elevating or lowering the T4 level. These people are frequently misdiagnosed as being hyperthyroid or hypothyroid, but they have no thyroid problem and need no treatment. http://64.233.167.104/search?q=cache:H-NZ_m3w2HsJ:www.endocrineweb.com/tests.html+normal+or+high+t4,+high+tsh,+low+t3&hl= en&start=7
