AF came today, i think?

i’m half way in denial and hoping for implantation bleeding instead but i’m pretty positive that’s not the case because of the negative tests i’m still getting even this morning, 13 dpo and 2 days into AF being due. When i took a test this morning a very obvious white line appeared as soon as the test window was clearing but then it went away and never got color to it. i’m discouraged because my husband actually has a 6 year old child already from a previous relationship and we want one so badly, but i’m struggling. it shouldn’t feel embarrassing or like i’m faulty, but it does. he reassured me he’s still excited and we’ll continue to try, he’s been great. i’m the one struggling to hold it together.
