I'm suddenly getting lower back pains, really tender breast,minor cramping and my period is 15 days late i went to the doctor the day before my period was supposed to come and took a test and everything was normal but who knows it could've been to early to tell maybe? I'm really scared and I don't want to be pregnant so far the IUD has given me lots of anxiety on wether or not it's working even though every time I check the doctor says it is I've had it for 8 months now and I dot know if is is normal I did get a almost month long light-ish period last month that went into this month by a couple of days but I'm still due for my period so could I be pregnant you think
