Hi I am a 19 year old female who is extremly confused about my cycle.. i have an irregular cycle either between (28 - 35) my last period started on the 14th of February and lasted 7 days. It usually begins heavy and the heavy flow lasts 4 days and lightens up for the remaining 3 days. This cycle my period started on the 18th of March. It started out light and had a brown/ red colour. Later that day it got heavy but not enough to fill a pad. For the remaining 6 days i have been spotting red, dark red, pink and brown which is un-usual for me it is usually bright red for 5 days and brown for the ending 2 days. This period has been on and off for a week and its bugging me i have slight cramps sore breasts headaches and moodswings. I have taken 2 pregnancy tests whilst bleeding and both have shown negative. My cervix is high soft sensitive and slightly open but im not pregnant according to these home pregnancy tests what should i do!?!?! Please help!
