I just finished my third pack and am willing to try a couple more to see if gets any better because it seemed like it was but now I'm not to sure. The first pack I had a little bit of spotting 2 weeks in and nausea and migraines most of the pack. I did have a light period at the end 5 days long (my period is 4 days off BC). The Second pack I had less headaches but a lot more spotting a break through bleeding through out the first 3 weeks of the pack the end of the pack finished okay, no problems. I started my 3rd pack and every thing has been going great all month but a couple days ago started freaking out because I thought I was pregnant. My breasts are extremely sore. I'm fatigued, feel nauseated, have headaches. I did eventually start a period but it's heavier than the last 2 packs The sore and tender breasts have happened every month which is normal for me off the pill as well but this month it started earlier and feels so much worse. I have noticed I have been gaining a little bit of wait the past three months and have been a little moody. I'll try a couple more months but if it doesn't get any better after that, I''m done.
