My last cycle was june 22 my next cycle supposed to started july 20 but didn't now i'm 5 days late with white discharge and cramps . i had sex a week before my period could i be pregnant if so when can i get a accurate reading on a pregnancy test?

You could be: Generally once you are late should be detectable on a pregnancy test but if ongoing doubts a further test could be taken 2 weeks later. The other possibility that needs to be checked urgently with discharge and cramps is infection. Would recommend seeing your doctor urgently to also exclude his possibility here. All the best.

Now: Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about 3 weeks for the embryo to make enough HCG to produce a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex, if you have sex. Get HPV vaccine
