Help!!!!

So I don’t know where else to post this and seeing as I’m 19 and ttc why not here!

Recently I’ve been having very detailed dreams about me being pregnant, I vividly see myself taking tests and them coming back positive and last night I dreamt that I told my mum and family and was able to feel the baby. I woke up this morning really down because it felt so real and i can remember all of it.

What does this mean, is it a sign or am I just wanting it that bad this has happened?

I’m 7 DPO and my period is due in 7 days

Any ideas? Should I test?
