So I actually had my period last month, and it didn't last as long as usual, only by like a day and a half but still. And I also kept having brown discharge for like a week after, and now I'm constantly having milky white/clear discharge. A week or so before I came on I began to feel incredibly nauseous most of the time. But I got my period so I didn't think anything of it. Now, 2 weeks after my period has ended I'm still feeling so nauseous all of the time, and it's worse in the morning and at night. I can feel the nauseousness in the back of my throat, like I want to throw up to make myself feel better. I've also been having mild cramps even though I'm not due on for another week and a half. And I've noticed I have slight pains in my abdomen, sometimes they are concentrated more on the side and to the back, kind of where my kidney is but not quite. I've been feeling like, slight muscle spasms I guess you could say, the best way to describe them would be like a baby kicking me. I know that's impossible but that's the best way I feel I can describe it. (I actually had a pregnancy scare about 5 months back where I completely missed 2 periods but they came back soo)

I don't know if I'm over thinking this but I don't know what else it could be. The constant nausea, the mild cramping when I'm nowhere near my period. The slight stomach pains. Do you think it is possible for me to be pregnant even though I've had my period?

Anything like advise or insight would be greatly appreciated :)

Sounds much more like a kidney infection or perhaps another type of infection.
Really does not sound like pregnancy.

Since it is two weeks past the very short period, you can try a pregnancy test, always use first urine of the morning as soon as you wake.

If negative, I think you should go to your doctor for exam.
