D dimer blood test symptoms and conditions

I am in my 2nd pack of Loestrin 24 FE and was put on them due to my extremely heavy bleeding. I am 39 years old and am not using this for birth control just period control. The first month went great, bled for 3 days and then stopped. My 2nd pack is going horrible. My legs are always cramping and hurting. In general I feel like I have the flu. I started my period after taking the second pack for 1 week and now at week three i am still bleeding and cramping. I am due to start taking the brown pills in three days and do not know if i am going to take them or skip them and go straight into the white pills again or just quit them all together. I do not feel that bleeding like this all the time is of any help. How many of you have experienced bleeding like this and continue the pill to see it quit? Also, I do not always take the pill at the same time, it sometimes varies by an hour or so.
