17DPO , AF delayed by 4days , BFN 😥

Vid

I had a miscarriage in first week of July. And we started trying immediately after the bleeding stopped. I took the hpt and it was all negative at 13dpo , 15dpo and 17dpo.

I had very very light brownish spotting yest. Usually I have spotting and AF would be here the next day. But AF is still not here yet. Not sure if I'm testing too early as I follow my 32days cycle. Or should I wait till next wed as it'll be 38days. Cause i had miscarriage on the 38th day in July.

Any success stories on getting BFP after 17DPO and no AF ? I don't know how to be positive already. Pls help ladies. Thank you.
