These adjectives all mean recurring or reappearing now and then. Something periodic occurs at regular or unsurprising intervals: periodic disruptions in electricity. Sporadic implies scattered, irregular, unpredictable, or isolated instances: spies who could manage only sporadic contact. Intermittent describes something that stops and starts, often with no discernable pattern: heard intermittent gunfire in the distance. What is occasional happens randomly and irregularly: a retired celebrity still making occasional appearances in public.periodic (ˌpɪərɪˈɒdɪk) adj1. happening or recurring at intervals; intermittent2. of, relating to, or resembling a period3.

Patient discussion about periodicQ. i just have my period last november 25 and ended on 28.when is my possible fertile and ovulation period please help me identify my fertile and ovulation periodA. If someone knew it, it'd solve the human race many problems with fertility. The problem is that ovulation (and thus, the period of possible fertility) happens 14 days BEFORE the onset of menses, so you know about it only retrospectively.
However there ways such as serial body temperature measuring, along with kits that measures the level of hormones in the urine in order to estimate the time of the coming ovulation, and help in timing intercourse.
You may read more about it here (www.mayoclinic.com/health/ovulation-signs/AN01521 ) but anyway, consulting a doctor (e.g. gynecologist) may be wise.
Q. can you get pregnant on your period? i know that you get pregnant when you ovulate and you ovulate in the middle of your menstration cycle, but people have told me that you can get pregnant on your period. can somebody help me out???A. It's possible, if your menses are long enough and your period is short enough, since semen can survive (and fertilize the ova) up to 3 days after intercourse. It's not common, but also not impossible. That's why the safe-days method isn't very effective in preventing pregnancy. Q. how should i support my wife during this tough period? A. first of all don't call it a tough period. a happy period might work better. although the wife can get annoyed by it. but she'll get annoyed from anything... just try to make her comfortable. foot massage , bubble baths, movies and popcorn.
it really depends on what kind of person is she and what she likes or not.
