Hallow Dear, Period delayed by one day should not cause you any stress. Of course, you had multiple intercourses around the ovulation period, and definitely within the fertile window which is a period of about a week around the day of ovulation. Soreness in the breasts and other breast symptoms and frequent urination and nausea/vomiting start about a week after the missed period, not so early. Tenderness in the breasts is more likely to be due to rough handling of the breasts. At this stage, you can confirm the status of pregnancy by Beta hCG test. Alternatively, you may perform pregnancy test on the overnight first morning urine sample after a week; earlier the test may report false negative results. Yes, white clumpy discharge is due to yeast or fungal infection. Only dietary changes will not cure you of it. You have to take some anti-fungal treatment - locally or systemically. Along with, use Lactobacilli vaginal preparations and perineal wash for speedy recovery. I understand that by now you are cured of flue . Please report to your Gynaecologist. Dr. Nishikant Shrotri
