Thank you, Sandi, you seem very knowledgeable and informed about this, I really appreciate you. An update: when all this started 3 weeks ago, my levels were at 36. I've been measured 2x/week since then and the levels have been 36, 46, 34, 43, 53, 45, 65. My doc said they look like they are improving, although slowly. Now I mentioned before that I have Graves Disease. I want to share my experience with you in part because you have a daughter who has this and this info may help. I was dx 7 years ago at 23 years old. I had a bout of hyperthyroidism that was detected, put on ptu made me very hypothyroid after a month, taken off, normal thyroid function for about a year. This trend continued for a few years, would become hyper about 1x every year, meds would overcorrect and then level out. Except a few years ago when I became hypo and it stayed there. My doc thought my thyroid may have burned itself out on its own. I went into levothyroxine 75mcg and was stable for 2 years, I got pregnant. They increase your levo dose gradually by 30% when you are pregnant. Everything seemed fine during pregnancy, no antibodies detected. At 30 weeks, my endo was so confident things going well she said that I didn't need further labs until 6 weeks after birth. Levels were stable. Well, hindsight 20/20 but I now strongly feel my thyroid shouldve been tested again at 34 and 38 wks, because looking back, I started to get hyperthyroidism symptoms. Very anxious, couldn't sleep, diarrhea... When I finally went labor, I vomitted and had diarrhea 10x in the first hours of going into labor, my contractions did dialate me but they were 4 minutes long (!!!) and never tightened together. I had an epidural and then when the baby began to suffocate due to the long contractions, an emergency c section. The baby was also small but healthy thank goodness, but she was only 6 lbs, in the 10th percentile and earlier measurements at 20 weeks showed her in 90th. I felt so out of control and dismayed by the whole experience. After the birth, I couldn't sleep, really for 2 months, sweating profusely, so anxious, dropped 40 lbs in 6 weeks, actually vomiting from anxiety, and other very severe symptoms. Being a first time Mom, I chaulked this all up to pregnancy and post partum healing. But after getting my tsh results 6 weeks later, or 4 months after my last tsh, I saw I was very hyperthyroid and it all just kinda clicked. I think I was hyper for a while and being overdosed on levo. This is also the time at 6 weeks post partum, that I began to bleed again and test showed my platlets low. My endocrine lowered my thyroid dose at 6 weeks from 112 to 88, but 2 weeks later my symptoms were very severe, and levels still hyper, she took me off of the dose completely and told me to restart at 75mcg 1 week later. Almost immediately after going off medicine, I was able to sleep and symptoms fading. Im afraid to got back on levo at this point and am holding off to get a baseline reading after its flushed out if my system. Interestingly, my platlets seem to be improving correlating with stopping the levo. Sorry for the long story, but if your daughter becomes pregnant one day (assuming she hasn't already), please let her know to watch for hyper signs and don't dismiss it as just normal pregnancy stuff as I did. Also, I was potentially hyper for 4 months, I just cant help but wonder how that relates to my platlets. Both my endocrine and hemo seem to think they aren't related but it just seems too coincidental. Also, the way my platlet levels are behaving, have you seen that before in your experience, they take a step up and a half step back? I'm just still so worried that I'm gonna go in and they will have fallen dramatically, I know Im not out of the woods yet, even if they make a full recovery I will always wonder if and when it will come back, just trying to understand where I am. Thank you, Sandi!
