So I did lug a pg test i own actually taken 3 of them and adjectives have come out unenthusiastic. would your breasts beome bigger that soon before it even would show up on a trial ? Any suggestions Please This is a common side effect of Mirena, which is adjectives during the first 2-3 months of insertion. It should dissipate over time.
