But I'm hoping someone can offer insight. Is it normal/possible to spot during your fertile week? By husband and I BD yesterday. Well technically it was late at night on Sunday so it was considered Monday already. Any who, I was fine. My fertile Window is from Monday - Sunday this week. Yesterday evening i noticed light brown spotting when i wiped. Along with EWCM but not too much. I brushed it off. Today, same thing. Not sure what this might mean. I know it can't be implantation since it's too soon and it's not my period. Anyone else experienced brown spotting during fertile week?
