I had a miscarriage on Oct 7. I bled for 10 days. I was to get my period on Nov. 4. But didn’t. I took ovulation tests since Nov. 7 and all showed a light line. We have been doing the bd every day. Yesterday we used Preseed for the first time. Today I had a spot of pink every time I went pee and cramping. Is it implantation??
