So I am 22 years old and my periods used to be somewhat irregular but for the past couple years they have been pretty consistent coming every 29 to 32 days. I also don't get any kind of pre-menstrual symptoms except for occasional bloating. For the last 2-3 weeks I have been experiencing some out-of-the-ordinary bodily functions like more frequent urination like every 2 hours or so, some slight cramping, gas, white slightly think discharge that doesn't smell or cause irritation, nipple tenderness and some slight swelling, and I've felt bloated the whole time. I calculated my period to start anywhere from March 8-13 and it hasn't come yet. I took a pregnancy test this morning and it came up negative. Could I still be pregnant? Could it be an ectopic pregnancy? If I'm not then what's up with all these random symptoms? Thank you for your time to offer me advice!!!
