Okay so i had my right ovary removed in november. I have had a period every month on the exact date glow says it will start. Well here i am now, 7 months later.

My period is 4 days late. I took a blue dye pregnacy test 2 days ago it was negative. (However i did take it afterwork, and i drink alot of fluids throughout day).

I dont even slightly feel a period coming on. Like normally my boobs are sorr and i cramp really bad or at least brown spot the day or so before its due. Nothing. Even just having very minimal stringy discharge.

So obviously i assumed negative test it will come. Well i am super moody. Like jumping down my poor guys throat anytime he speaks and thats not me lol. I also have developed a mouth ulcer/canker sore which i never get. And we take temps at work daily normal 98.2-98.3. Well i decided let me check today cuz google said so lol. 99.0. Ive also wanted chicken noodle soup (i normally dont care for even when sick) 4 days in a row.

I plan to buy a test again tomorrow. Anyone ever experience similar??
