question: I have been having quite bad lower back pain, in the pelvis region for close to 3 weeks now.. I have had constant spotting between periods and they have been very irregular. I have had the contraceptive implant put in about 10 months ago.. I have previously had cin2 but had lettz procedure to remove it and several smears which have come back black although i am overdue one now. I had severe spd in both my pregnancies so im wondering could the pain be related to this. Or my biggest fear is they are cancer symptoms. I am an otherwise healthy 34 year old female. Your opinion would be appreciated. Thank you.
