im worried because i didnt take my pills as i had to,for example i missed 3 and then take all of the three in one day and had sex with my husband and when i had my period it was so irregular it only lasted 3 days and used 3 pads with a little spotting they weren't full i took a test and it was negative should i wait to take another test or it was the efect from not taking my pilss right?
