Important - we don't eat cows. We eat steer. Cows have been bred over the decades and centuries to give birth and milk, not to yield meat. That's important, because some cows are heavier than their steer counterparts (Holsteins, for example).
Also very dangerous is inducing a miscarriage by taking strong medications prescribed for other ailments and many of the ways to induce a miscarriage can actually end in loss of life or other very serious consequences.
Re: Is there a way to induce your period when it's late? Maybe I am abnormal or I'm just having a placebo effect but one aspirin a day for a couple of days will induce mine even if it isn't time for it. I rarely take any meds at all so maybe that's the reason? I'm not advocating you do this though....
