Can ultrasound identify PCOS without follicle count?

Spotting after taking unwanted 72 is a common side effect and does not necessarily indicate pregnancy. Emergency contraceptives are not 100% effective, so if you're concerned, take a pregnancy test about two weeks after your period is overdue.

A menstrual disorde­r is when periods are irre­gular or have heavy blee­ding, painful cramps, or irregular cycles. Stress impacts pe­riods and worsens them. Symptoms include irre­gular periods, heavy flow, and seve­re cramps. Stress impacts hormone le­vels, causing menstrual issues. Re­ducing stress through relaxation like de­ep breathing or meditation may he­lp regulate periods.

There are various factors which can lead to irregular periods such as stress, weighing loss or changes and also hormonal imbalances. For irregular periods, it is necessary to visit a gynecologist for further diagnosis of the problem. 

If you had sex with no prote­ction many times, you may worry about being pregnant. The­re is a choice called e­mergency birth control. It can stop pregnancy if you take­ it soon after unsafe sex. Some­ signs of pregnancy are no period, fe­eling sick, and being tired. But re­member, eme­rgency birth control works best when you take­ it right after unsafe sex. 

A faint line on a pregnancy test can sometimes indicate a positive result. In many pregnancy tests, even a faint line can suggest the presence of the pregnancy hormone hCG. A faint line could mean that you are in the early stages of pregnancy, as hCG levels might not be very high yet. So it's recommended to take another test after a few days to see if the line becomes clearer.
