Hi! Im in the same position as you are. me and my partner are also trying, i was having the exact same symptoms as you describe, as well as feeling sick and I was 5 days late when i did a pregnancy test over the weekend, which came out negavtive but ive still not had a period. They say most tests can detect pregnancy 4 days before your period is due, but that youre best to wait until after, which you said you have done! I would wait another few days or so and if still no period then do a test again. Really just a waiting game, which is the worst part! :)
