Advice!!

Brittiny • Tue, Jul 28

I od'd on CD14 with positive OPK and have a 28 day cycle. I then took more OPK tests on CD20 and had them positive for 4 days straight until i ran out. I BD everyday on my fertile period and almost everyday a week after throughout the month. AF is due tom. Why am i taking so long getting pregnant when im only 25?? Need advice!!
