Hello,
You seem to be having the symptoms of metrorrhagia(heavy periods).Various factors causing it are endometriosis,ectopic pregnancy,hormone imbalance,endometrial hyperplasia,polyps,use of IUD’s and depo shots, sexually transmitted diseases,PCOS and benign and malignant pathologies of the uterus.
I suggest you to get it checked from a gynecologist to confirm the diagnosis.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
I didn't miss a pill but I wasn't consistent with the time I would take it.
yes you may be pregnant try to recall weather u missed any pill last month or u had any febrile illness needing antibiotics as this decreases the efficacy of birth control pills. you better go for a pregnancy test at the earliest.
