Can you show signs b4 positive test?

Tristen

what do y’all think? i have irregular periods so idk when my period is for certain... but i have been having unprotected sex got 3 week’s almost and i ovulation a week ago/a little over a week bc i got a positive ovulation test. but i’ve been experiencing some symptoms:

* HORRIBLE mood swings

* headaches almost everyday

* feeling sick

* super tired all the time

* lower back pain

but i took a pregnancy test 3 days ago and it was negative. so i was wondering can you show signs before a positive pregnancy test? thanks!
