Hi, thanks for using HCM.Implantation
occurs on 10th day after fertilization, as you had intercourse 7 days back, less likely to be implantation bleeding and as you have regular period, your were in a safe period, so chances of conception are less.
Increased frequency of urination could be due to urinary tract infection
. Get urine test done after consulting your doctor.
Some amount of white discharge is seen before start of menstrual bleed, which is normal, not to worry.
Any abnormal excess discharge need to be investigated.
Hope this helps you.
