It's usually difficult to conceive at such times in the menstrual calendar. However, remember that no contraceptive is entirely foolproof although using it correctly reduces the risk significantly. If there are any unusual signs or symptoms, it may be a good idea to do a pregnancy test to be sure.

Worrying when pe­riods are late after unprote­cted sex is normal. Stress can disrupt me­nstrual cycles, yes. But pregnancy or hormonal shifts might also cause­ delays. Anxiousness or tension indicate­ stress. Taking an at-home pregnancy te­st provides certainty. Managing stress is ke­y too - exercise, confiding in frie­nds. Periods will return when the­ root issue resolves.

There could be a delay in menstrual cycle because of many reasons like stress, hormonal problems and some medical conditions. Nevertheless, you had no protection thus pregnancy is always a possibility for you. A pregnancy test and a visit to the gynecologist will be necessary for proper evaluation.

You may be having numerous bodily changes. The signs you described–like shorter periods, more belly fat, itching in the private area, and constant fatigue–could be a result of irregular hormones. Ailments such as those related to the thyroid gland or other hormone shifts may cause these irregularities.

If your period is late, it’s okay to worry. Stress can throw off your cycle, causing it to be late or even completely miss it. Feeling tired or throwing up could also be symptoms of stress. If you took the morning-after pill and then got your period, you probably aren’t pregnant. It is better to wait a little longer and see if it comes. If your period still hasn’t shown up, take a test just to be sure.
