TTC at 33

Joanna

So I was supposed to get my period on 12/15 and I have to get it. Earlier this week I tested and both were negative. So I assumed if I wait until Friday morning and test it should come up....well nope it was negative again 😢 I’m very regular with my period and based on this app I’m on time or maybe a day late......but not a whole week 😱 what do you ladies think I should do next? Help!!!
