Long story . Test or no ?

Destiny

So after I had my son in March my periods started coming 1m pp. every 26 days too, was never late. Last month However my period came on CD 40 😑

My period was suppose to start yesterday and hasn’t. Me and my so stopped “trying trying” to relieve stress Incase it doesn’t happen .

Well he’s pulled out a couple times and then went back to work . Should i test or wait? I don’t wanna waste money on tests again for nothing 🤷🏽‍♀️
