Hello! Although your sore nipples, cramps,
fatigue and thin
vaginal discharge could be early signs of
pregnancy, they could be caused by other things, too. Taking a pregnancy test before your next period is due to start is too early; the best time to take a pregnancy test is after you're late for your period.
Having frequent sex increases your odds for getting pregnant, but the most important time to have sex is around ovulation, as your egg only survives for about 24 hours in your fallopian tubes. (Ovulation typically occurs 12 to 14 days prior to the onset of each period.) If you do conceive, it can take another 6 to 12 days for
implantation to occur, and two or three more days for a home pregnancy test to turn positive.
Many couples get frustrated when they don't conceive within a month or two of trying to get pregnant. However, during any given cycle, your chances of getting pregnant are only around 15 to 25% (as long as both you and your partner are fertile and otherwise healthy). Statistically, about half of couples who are trying to conceive do so within 3 months, roughly 75% conceive within 6 months, and nearly 90% are pregnant by one year.
I suggest you wait until your period is late to take another home pregnancy test. If it's positive, you have your answer. If it's negative, wait another 2 or 3 days before taking it again. If it's still negative and your period hasn't started, call your doctor for advice.
I hope that all helps, and good luck!
