I NEED SOME ADVICE!!!!!

Anya

So I’m trying to get pregnant and I had sex from June 1-3 . I missed my period got excited and took a text on June 7th the test came back negative. My period came June 20-24. I was supposed to be ovulating 3rd -9th of July....July 7th I woke up and I’m bleeding I’m confused because my period is two weeks early.I called my sister in law and she told me that it could be implantation and I should take a test because the same thing happen to her with her 3rd child...took the test and it came back negative.... So I accept the fact that it could be my period..... the bleeding stopped the nigh and in the middle of the afternoon the next day I was bleeding.... why is this happening? Did I have a miscarriage? I’m freaking out help me please....I’m trying to go to the doctor just to make sure that everything is fine
