period like implantation bleeding

Bailey

Okay hear me out, I had my period the 4th-8th of September. I started LH testing around the 13th and I knew my peak was coming soon but ran out of strips(I believe I had my peak the 15th or 16th according to LH strips) today is the 21st and I’ve started bleeding again. It was light on the 20th, still is light enough for me to wear one tampon all day and it be full. I’m not sure if somethings up and I just had my period twice this month or it could be implantation bleeding. I also just took another LH test and it’s pretty high(I know ovulation bleeding is a thing but I’ve never experienced that. Down below is the LH test I JUST took 9/21)
