Please PLEASE help!

This is literally my first month trying and I'm still learning and impatienly waiting to test! My boobs are so sore and big, it usually happens before my period but it happened way sooner this time and they feel the biggest they have ever felt! One app says my period is due today and to test today and another says take a test in 5 days if my period doesn't come in two 🫣

The top test I toke 3 days ago and came up negative and the next morning the second line appeared!

The bottom on I took this morning before work and when I got home the second line appeared!!!

I am losing my mind, what does this mean? 😬😬🤞🏽🤞🏽
