Hello dear
I understand your concern
Missed period is confirmation sign of
pregnancy.
Nausea is variable symptoms of pregnancy. It may be due to stress and gastrointestinal disturbance.
If you have used condom properly then chance of pregnancy is less.
Some time delay period by the 3-4 days is normal.
If period is delayed by the 7-8 days then go for pregnancy test and or bllod HCG to confirm the pregnancy.
If you will be pregnant then still you can terminate by using abortion pill under the observation of
OBGYN specialist.
In absence of pregnancy other cause of delayed period like hormonal imbalance, stress, PCOS,
endometriosis,
thyroid dysfunction should be rule out by consulting the OBGYN specialist after proper investigations.
Period can be induced by
progesterone pill in the absence of pregnancy.
Avoid stress, do regular exercise and take healthy diet, drink plenty of water.
Hope this may help you
