 [ Symptoms ] does drinking tea help boost fertility  i have heard that drinking 2 cups of tea a day will help increase your chances of getting pregnant but i have also heard the opposite that it will decrease your chances [ Disease ] yes any time that you have unprotected sex there is a possibility of a pregnancy of course there are only a few days per month that ovulation occurs and contraception is most likely just before your period is not one of them but just in case you should do a few pregnancy tests in a few weeks if you have not had a normal period being only four days late is much too soon to worry about it
