This is my first month of birth control pills and just finished the 2nd week of active pills. I got some spotting 2 days ago, but today I got a bit of cramps and started bleeding more. I use the diva cup so i inserted it and 12 hours later the cup is full to the brim. I understand that there's breakthrough bleeding , but is it normal to be this much? I have not missed a pill and have been taking them constantly, only taking it a half hour late, at the most. I also do regularly have very heavy periods. so I don't know if its a factor. Regularly without my pill , my period would have started around the 6th or 7th of the month
