Please help!

Nicole

Okay so I had my mirena iud removed on the 11th of February. I started bleeding on the 12th- 16th. It was like a normal period, possibly a little heavier. I then had a tiny bit of spotting on the 18th. These opks are in order top to bottom 23rd at night 24th morning and 24th 1 pm. They look positive to me. But today I am bleeding again. Please help
