I had spotting at 8 dpo and this morning at 9 dpo I took a pregnancy test (the bottom one in the picture) and I swear I saw a line right away so I ripped it apart to take a better look and then I had started bleeding more heavily and red. My period wasn't due till july 24th. I never have early periods and I'm positive I did ovulate on the 10th of july because I used opks. What is going on?
