I am 19 , my periods are usually regular. I ended up getting depressed for many reasons and lost ALOT of weight . I weighed 130 then down to 104 within less than a month , my period usually starts the beginning of the month and I BARELY got it and it only last a day maybe even two if anything but hardly any blood . I’ve been really sick , to morning sickness , headaches, sensitive to smells , heat strokes , back pain, is there a chance I can be pregnant even though I got my period ?

A friend told me even if the test is negative I might still have a chance of being pregnant, is she correct?

Sorry this is so long I really need help💜🙏🏾
