Confused

KB

So so confused what's going on with my body....

The Mr and I are ttc #1

Im I'm on cycle day 34 usually have a 28 day cycle of taken 3 tests all BFN

Iv had symptoms or what I believe are pregnancy symptoms but today iv been hit with a terrible cold and I have heard from my friend who experienced this that it's was her sign she was having a baby so fingers crossed but when should I test next?
