I been having cramping on and off and having lower back pain . I have had unprotected sex 3 days while I was ovulating. I also noticed one time I had white clumpy discharge . I don t notice it smelling. I been getting sick to my stomach and very sensitive to certain foods. My period is not due until 2 weeks. I did have a miscarriage about a month ago, but my Doctor told me I was back to normal and my numbers were back to normal, so it s hard to believe that I got pregnant so soon after.
