I have been taking the progeterone only pill (mini-pill) for about a year and a half now. It's the only bc pill I've ever taken, and for the most part I have never really had any weird side effects. However, over the last year the frequency that I've gotten migraine headaches was increasing substantially, from about 3 per month to about 10 per month. About 2/3 of them were still highly coincidentally timed with my cycle, so I talked to my doctor about switching me to one of the longer-cycle drugs (Seasonale, I think?) and he agreed to try it. I was supposed to switch over to the new pill at the start of my next period, but I missed that because TOM got weird around the same time... either my period came after 2.5 weeks, or I had spotting for several days for the first time in my life... and then got my period another 3 weeks later. Ugh! So I've still been taking the mini-pill, but now I am almost out of them.
The issues with my TOM getting weird were within about two months of when I started trying to lose weight, after I had been losing at a rate of about 2 lbs / week for around 8 weeks or so. However, when I went to write up this post just now I realized that over the last 4 - 6 weeks, my migraines have really been a lot better. I think maybe 2 in that time period, so a HUGE improvement over where they had been.
So I am thinking that losing weight is wreaking havoc on my hormones anyway, but at least my body is already used to taking the mini-pill. I think that I've heard that the pills that contain estrogen tend to cause people to gain weight more commonly than the mini-pill does. Since I'm down around 30 pounds now since I started in october, I'm not super excited about the idea of changing something that would cause my progress to stall. At the same time though, only having 4 periods a year would be pretty fantastic.

So have any of you switched from the mini-pill to an estrogen containing pill during your weight loss journey? Did you notice it causing any effect on your downwards progress, or any other significant side effects that were either good or bad? I'd love any input that could help me decide whether to stick with the mini-pill or finally start the new estrogen-containing pill.




) i've never heard about seasonale though... maybe i should look into it!
