I am 14 and the months ago started microglia 30 contraception pill because my periods cause me quite a lot of emotional stress, I skipped the first gap between the first two packets and then when it came to the second gap I had to skip it because there was quite a lot of important stuff going on at that time
About two thirds through the third packet my period started even though I haven't missed any of the pills, on the fourth day I went to the doctor because I needed more of the pills and I explained what happened and she said that can be normal if you go for too many pills without a break.
Normally before I started my pills it was 4 days of painless constant crying. By it is now my seventh day of this period and it's still going, it is still the morning so I don't know if it will finish today but this whole period has been slightly less crying but a lot of cramps and i never got cramps before I started these pills and got this period, and in my opinion they are quite bad. But saying that I have a low pain threshold.
