Late period

Hi all,

I am 1 week late for my periods I am normally on time, I did however take emergency conception this month and started a new job which has been a big change and stressful.
I also never have a late period more than a few days either side.

I have had all the usual monthly stuff tired, cranky hungry like leading to a period but still nothing.

I took 3 tests 1 on day 1 of being late -negative 2 on day 3 - negative for both & 1 on day 5 which I swear I saw a faint line. The afternoon before I went to my doctor and got bloods and he rang and said test was negative. He advised period should be here soon.

I’ve had some white discharge today, could that be my period on its way??

How reliable are the blood test considering I am now a week late, surely something would’ve shown up in the blood test. The only time we had unprotected sex, didn’t cum inside was 2 days after my last period.

Please help put my mind at ease. I’m trying to relax and not buy anymore tests but I wish my
period would just come.
