Discouraged

So today it's officially 3 weeks since I missed my period...I have taken 3 pregnancy test which I took one this morning and it was negative. We had sex yesterday and I started bleeding a little and today it's just slightly pink. Today marks our 1 year anniversary as husband and wife I would of loved to give him that surprise unfortunately I can't. I feel so discouraged I have never been this late and I feel dumb for even thinking I was pregnant 😢
