2.If these hormones prevent ovulation which lessens the lining of her uterus, why is it normal for a girl's period not to come in 3 months with the shot, but a girl on the pill must shed once a month?
3.Can pill users take the active pills continuously so she gets her period every 3 months? Would it be safe?
4. Whats the difference in the doseage between the two?
....sorry but this is unclear to me... i hope someone could help me with these questions...
1. Depo contains only a progestin. Most pills used today are combination pills, and contain progestin and estrogen. There are progestin only pills, but they're not widely used.
2. Some women do not menstruate on Depo because the hormone level is constant, whereas on the pill, there are 3 weeks of active pills, then a week of inactive pills. The lack of hormones in the body during that final week trigger a "period."
3. The pill can be used for several months consecutively. Seasonale is a brand of birth control marketed for this reason.
4. Depo Provera has 150mg of medroxyprogesterone. The pill varies based on brand, but typically has around 20-35mcg (micrograms) of estrogen and progestin.
