Hi,
My husband and I have been trying to concieve for about a year and half. My period was delayed by a week(week5) and I got my periods on Aug 21. It usually lasts 5 days with moderate flow. Today is my 4 th day and there is minimal spotting. I had backpain, slight cramps and sensitive nipples around week 3. I never get back pain or cramps beyond day 2 of my period. I now have mild cramps and backpain with tailbone pain which is quite painful. I took a pregnancy test and came back negative on the 21st. Could I still be pregnant?
