Could i be pregnant or just stressed?

Am 6 DPO and im getting some

realy strange symptoms i dont

know if its pregnancy or just stress

as my mum has just passed away.

Symptoms im currently getting are:

constant Backache and painful legs.

Nausea. headaches. Mood swings.

Cant count how many times ive

bitten my poor partners head off.

lm constantly exhausted no matter

how much sleep i get. Getting slight

tummy cramps. I dont really want to

do a pregnancy test until ive

actually missed my period as scared

of being disappointed again. Been

ttc for just 2 years now. Have 1

daughter from a previous

relationship. And have had an ectopic

pregnancy and found out i have PCOS.
