I'm pretty sure I'm 4-6dpo? I didn't temp or opk this month, but I have had ewcm for about 6 days.. Is this normal?
What makes you think you already O'd?
I'm on cd 17 and haven't O'd yet and have had abundant ewcm since cd 9. I think everyone is different and it could be your normal to have lots of days of ewcm. Before I got pregnant with DS I hardly ever had ewcm... Some months I had none and sometimes only for 1 day. Now I get it a lot more often. I think it just depends on your body.
Sorry I'm not more help :/
