I'm in a very similar situation to you. I'm having some very similar symptoms and feeling a little how I was the month I was pregnant (sadly ended in a chemical) so I'm hoping it is a positive sign. I'm trying not to read into it too much as it's such early days, although it's so hard not to!
I'm so sorry to hear this

don't feel stupid for getting excited as it's normal to feel that way and as others have said, hopefully it will help having a support network around you of people that know about it. I also spoke to my doctor after my chemical who was really lovely and talked me through it and trying again if that's something you might also find helpful
