Hi this is Jyothi, age 29 yrs, with a history of spontaneous abortion at 6 weeks in the year 2010, later diagnosed with Toxic multinodular goiter (very fluctuant) and on treatment with PTU- 50mg, for few weeks. Was pregnant and my doc advised PTU 50mg (2 tablets in the morning and thyronorm - 100mg) and again PTU 50mg alone (2 tablets in the night). Was informed this is Block Replacement therapy. Mainting the free T4 levels. Am Currently 23rd week, i.e 6 th month. During my 13th week of pregnancy i had observed spotting for few in and then subsided, was advised bed rest for few weeks. My Ultrasound and TIFFA scan is normal. Am a working woman, but my doctor says to take adequate rest, which is difficult right now as my company only gives 3 months of maternity leave for the delivery. So is it really needed to take rest, i.e apply my maternity leave during 7 th month onwards, as my scan reports say every thing is normal. I do have fears bcoz of my past history of miscarriage. Also for how long should i continue this thyroid medication, i.e should i still continue them even during my 7, 8, 9th months of pregnancy and immediately after delivery? Right now my free T4 levels are in normal, but since it is always fluctuant my doctor is trying to maintain my levels within normal by either changing my dose(same PTU and Thyronorm). Please help.
