Your fertile period should be around 2 weeks from now. The best way to know is to get ovulation tests and I think they sell ones to see if you're fertile. Find an ovulation calendar online and type in all your info and bit should tell you your best days. Gl
If you don't have the money for an ovulation test kit, right about the last day of your flow, have sex. Then do it again every three days until either the beginning of your next period, or until you get a positive on a pregnancy test, whichever comes first. :) If you have sex every three days, you will always have viable sperm in your reproductive tract due to the long life of sperm in the woman's system.
Money doesn't matters here but I don't know when are my fertil days to check the ovulation so I asked for suggestions..:)
