hey there, for the last couple of weeks I have been increasingly tired, really faint, cant concentrate and bad head aches. Alongside with that, I have missed my period by a week so far and last month was the same, it was late a week and I have buring sensation in my lower right pelvic. I dont feel like myself, im bloated, not hungry and when I do eat, i feel nausea afterwards. My lower back is killing me!
