I have been experiencing lower abdominal cramping/pinching consistantly for 2 weeks, along with fatigue, dizziness, increase in urination. Just within the past 3 days my lower back/tailbone area has been a dull achey feeling almost like what I get with my regular menstrual cramps, my breasts have been tender and off and on I have been nauseous. According to my menstrual and ovulation calendar, I am supposed to start my cycle in two days. I m having similar symptoms but I don t know. Maybe this is wishful thinking that I m pregnant because my husband and I just started trying almost 4 weeks ago.
