Hi i am 24 yrs old and just had my third child about 6 mo ago, i received the mirena iud about 6 wks after delivery, and since then i have been having bad headaches, heart palpitations, bad dry skin, and i actually gained another 30 lbs when with my other kids i lost weight afterwards..and i have been very very moody! my ob says the iud cant cause that many side effects because all the hormones are immediately absorbed into my uterus is this true because i am beggining to think they lie to me
