Postpartum Thyroid issues?

Holly • Rico 13.01.17 💚 & Zoe 03.07.18 💜
Anyone developed hyperthyroidism postpartum? Would love to hear if you have and what treatment or advice  was offered to you?
 (I used to have underactive thyroid and was treated during pregnancy - my tsh levels weren't tested again til 6 weeks postpartum where dr realised I'd gone the other way and told me to stop taking levothyroxine). Thanks mummies
