HI M.!
I have two small boys that exhaust me by the end of the day as well and we got pregnant with the first one because 'alas!' I forgot to take my pills. I have never been happy with BC pills, the hormones were always off for me, I couldn't find one that worked....I am allergic to the latex in condoms (and frankly, when you are married, who wants to use them?) and who wants to get up and run to the bathroom to use spermacides when its gettin hot and heavy? Not me, after a long day with boys, if we get it goin, it needs to stay goin or I'm gonna fall asleep! ha ha
After the birth of my second child in 2004, I opted for the IUD (Intrauterine Device) I chose the Mirena brand IUD. It was covered by my insurance, but did have to pay the standard office co-pay and also a fee ($60) for the doctor to insert it(guess they don't make enough money) I chose the 5 year one, but they also have a 10-year one. I have NEVER had any problems with it. I LOOOOOOVE IT!! There is no maintenance, AND, I haven't had a period since BEFORE my second son was born. I had it inserted at my 6-wk check-up after baby and haven't had a period or cramps since then. It is wonderful!! I have recommended it to many people. I still have a couple years left on this one, but when its time to change, I'm going to opt for the 10-year one. We don't plan on having any more kids, and if we did...for some strange reason (like a sudden case of amnesia..ha ha) it can easily be removed in one office visit, and you can get pregnant right away.
You can look up information online about it on their website (www.mirena-us.com) Talk to your doctor and I'm sure he/she can help you decide which brand you prefer. I love the Mirena and will use it forever!!!
I hope this helps...if you have any more questions, please do not hesitate to email me!!
Take care and good luck!
