At my last RE appointment our plan was to continue Synthroid and have a blood draw in 2 weeks (which would be this coming Wednesday). However, being that for 2 months I had a cycle on my own, RE said that if I had one on my own before my appointment to come in for blood work so we don't miss this month. So Friday I had spotting twice. Once in the morning and once at lunch time. They had me come in because we thought it would be the real deal by Friday evening. I had my blood drawn and haven't had any bleeding since. W.T.H. ugh.
