Have you put on the weight recently, or have you been like that for a few years? If a female gains/loses weight in a short span of time it can affect fertility and cause you to not have a cycle at all. Sorta the bodies way of protecting itself FROM getting pregnant.
If you've not, it would be in your better interests to see a doctor. I understand they cost a lot (trust me.. I know) but they can figure out what's going on and if you DO get pregnant you'll need to be seeing one quite frequently. Plus the cost of a child is 100x more than a doctor appointment will be, so it's something to think about----
im 24 years old and i never was irregular til now!!! i havent seen a cycle 4 real since may they usually last 5 to 6 days and no i never seen a doctor they cost too much and i dont have any insurance right now and yea i am a little bit over weight
There is no proof Geritol does anything (it makes no claim to help fertility--I personally have never recommended it. It is just a vitamin) and prenatals only give your body what it needs for when you do get pregnant--it doesn't help fertility.
A female ovulates before she has a menstrual cycle, as it's the ovulation that causes you to menstruate. Therefor in a lot of cases, lack of a cycle indicates lack of ovulation. A few questions might help a little more. How old are you, do you have regular cycles and if so how long are they usually--if not, how often do you have one? Have you ever seen a doctor, do you have any underlying heath issues, are you overweight?
