Cramping since O

Kr

I had cramping and heavy watery CM 4 nights ago. The next morning I had EWCM and a couple small spots of blood in it. Had sex an hour after seeing this. Assuming that was my ovulation. I have had light cramps and dull aches in my uterus off and on since. This would be my fifth pregnancy and 4th baby if so. Anyone else? Due for period in about 12 days
