I was sick two months ago with a streptocal throat infection and was on a huge amount of antiobiotics i was taking 2900mg in total per day. Then last month i got an ear infection as even the skin inside the ear was very infected. Then this month i got a very sore throat and bad flu but i decided not to go to the doctor and get antiobiotics because i feel that my body is getting so sick cause ive taken two lots of antiobiotics in two months. After a few days my throat and flu got better gradually. When i was first sick with the streptocal throat infection i was on the pill for a week and i stopped it. A week after i got better i had unprotected sex but im married. I got my period in april but it was two weeks late. Im half way into my cycle now and i get brown blood but its so light. Can someone please explain whats wrong with me? Thank you.
