Hi Ashley, It sounds like you aren’t pregnant at this time if both urine and blood tests were negative. However your symptoms could be related to PMS and if your cycles are off a bit it could be a bit more severe. I’d check in with your doctor and continue to keep good track with a menstrual/bleeding/symptom calendar. Depending on whether or not you are trying to get pregnant he/she can try some different things to get you back on track. Good luck!
