Hi, I am 28 years old female and it's been 1.5 years of marriage. I have been trying to conceive for last 3-4 months but not regularly. This time I have gone through follicular monitoring to know my ovulation. Day before yesterday my egg was 18. 3 mm and today it has been raptured. Also, free fluid has been seen in wpo. I want to know is it my last day of fertile window or shall we try for more couple of days? And, what this fluid signifies exactly? My husband's sperm count was 40 million, so it is good enough to get pregnant? Pls answer, I am really hoping to resolve this dilemma.
