Well ladies

I had my thyroid removed in 2016 and since then my levels had been all over the place. In nov of 2018 they were like 23.48 then March this year dropped to 2.23. I went in July to do them again and they were at .22 I’m now 10 days late on my period. I took a test and got a bfn. So far I have no signs that af is even going to show her ugly face. Usually I get cramps a day before and a tore up stomach the day before every month. I tried to not get my hopes up but of course I did like everyone other woman does when af is late. I’ve never been this late before. Should I continue to wait or request some blood work? I’m just confused. Mood swings with a lot of white creamy discharge.
