could I be or could I not be...

so last month I'm pretty sure I only spotted one time. I'm thinking I was stressed from a family funeral and couldn't remember if I had a period or not. This month AF hasn't came yet. since the first my nipples have been hurting and very sensitive. I've had some implantation bleeding on the 3rd of June. The 4th nothing. I did take a test and it came back negative. 😔😢 But on the 5th after sex I was lightly bleeding.. very light pink and light red. Today on the 6th I'm having light bleeding. it's not dark its very light red/pink also. Every month I'm praying that this is it. It's finally my chance in life.
