AF started on 10/24 and ended 10/29, it was pretty normal through out, on 11/4 I woke up with relly bad cramps and I know I must have had a cyst because I have had them before , after some advil I felt great. This morning my DH and I BD and after when I got up I went into the bathroom and I have been spotting light pink. Is that normal? it's never happened to me and AF is not due until 11/20. My cycles are very regular 28 days. I honestly dont know the exact dates of BDing my husband and I work alot and sometimes he works overnight but I know that it has happened a couple of times between 10/29 and this morning.
