I have a problem. I had my cycle on dec 2 and I had sex dec14-16 Okay my cycle came on Jan 2 but it started off very light and brown and then became dark and heavy it lasted for 4 days but my cycle usually lasts six.
After my cycle I have had major back pain and also extreme nausea and fatigue. My hormones are going crazy could I be pregnant? Plaese help

Thanks
