Preseed question

Sharee • Loving life with my sweet rainbow baby! 💗Amelia Nicole💗
How long does it stay in you? 
I had light/medium EWCM for a few days but yesterday it seemed like I was dry down there and my temps haven't shown ovulation yet so I decided to try Preseed. 
I didn't use much, I only went to the first line. But today it seems like I have A TON of EWCM. Sorry for the tmi!
Could that just be left over Preseed and semen? 
AND, if we don't BD tonight should my chances still be ok? (Hubby's been working a lot 😔)
