Hi I am 22 and I have been on Lutera birth control for 6 months now. I am sexually active. Last month I had an eight day long period that was other wise normal. Then about 11 days later I had a very very light period or spotting not sure which ( not enough blood to use a tampon or pad just liners only changing them once every 6-8 hours and not completely full then). I am wondering how to figure when my next period should be would I count from the first or second? And if anyone can tell me what caused the second?
Thanks in advance for any help
