Had my last period October 7-11. Skipped a period November which since I miss carried in June has been the normal. Why am I skipping every other month and now was suppose to start af according to glow last Friday and morning. My boobs hurt like mad, have constipation like crazy and a "icky" feeling and lately have been feeling tight in my lower abdomen region and if I move wrong get a bad twinge down there also. What is going on? I am terrified to take pregnancy tests cause they always come back negative. We have been ttc for 9 mo for baby #3.
