Possibilities of pregnancy ?


So I’m trying for my 2nd little bubba, I took a pregnancy test a week after having sex 4 times and it came up negative, it’s been almost 2 weeks since having sec and I’m starting to get little cramps( little compared to my period like cramps) and I’ve had similar pregnancy discharge which is white/ clear stringy discharge. How long should I wait to take another pregnancy test and ya that a positive sign of pregnancy? 😣
