If you want to save some money, you can go to your local MCHC family planning clinic and get the pill for $1 instead of whatever it costs at Watsons. They have obgyns there who will discuss with you your various options (not only the pill, but also if you would consider IUDs, they have that option as well). To go on hormonal birth control, they prefer you to go when you have your period to make sure that you are not currently pregnant.
I'm on Cerazette, which is the progesterone-only pill that breastfeeding mothers take. I am no longer breastfeeding, but the estrogen in the regular pill gives me migraines and so the obgyn at the MCHC told me I should continue taking it even though I'm no longer breastfeeding. It has a slightly higher rate of failure than other birth control pills, which I am "accepting" off (we do plan to have another child, so if the pill failed, it wouldn't be devastating) but for me, not having the awful side effects of the regular pill make it worth the risk. At the MCHC, they gave me 6 months supply for the $1 - previously I was paying something like $150 or so a month at Watsons!! I wish someone had told me about the MCHC earlier!!!
