I removed my mirena iud  myself on the 7th of January due to having a lot of complications with it . I've had sex 3 times unprotected . I had a normal period from the from the 8th to the 12th of January so I'm due for my period until the 2nd of February however I started a light /medium bleed on Monday the 23rd of January . I've taken two home pregnancy tests and they have come back negative .... my question is could I be pregnant and it's too early to pick up or what could the early bleeding be ? I would appreciate any advise please !!
