Am I wrong to be nervous?

Vivian

My fiancé and I have been ttc since our mc Jan 2017. We have had a couple chemicals since then. Every time during my ttw I say I’m not going to symptom spot. And I try really hard not too but some months are harder than others and of course your let down even more once af shows. It’s so hard to tell the difference sometimes between early pregnancy and pms. Ugh it’s so freaking frustrating. But with that being said my cycle is usually 27-28 or has been since my last chemical and here I am cycle day 31. The day before af was due I tested bfn. And we are here 3 days later. I’m terrified to test again! I don’t want to get my hopes up anymore and have them crashed. What do I do? Give it a few more days or test? Any encouraging stories of people that have been thru this?
