I always used to get my periods on time. My period cycle has been delayed. I was supposed to get it last month on 28th. STill waiting for it :( I m sexually active. Not pregnant. taken urine test twice. no thyroid problem. i went to a doc and she asked to take period long medicine (10 tabs). Still didn't get it. i took an ipill 2 months ago. however the immediate period was on time and there were no issues. Please help.
