Why am I having light periods since 2022?

Light red spotting after not getting a period for one month may indicate implantation bleeding, hormonal imbalance problems or complications to the pregnancy itself. It is advisable to see a gynecologist for proper medical checkup and also receive an accurate diagnosis. 

Periods can sometimes be late due to stress, changes in life, or even illness. Since you used protection, the chances of you becoming pregnant are lower. In case, the delay continues you can do a home pregnancy test for reassurance. Tracking your period is always a good idea. 

Early pregnancy spotting isn't always conce­rning, notably around your expected pe­riod. With rising hCG levels, spotting may signal implantation. Howeve­r, heavy bleeding warrants me­dical attention, especially if accompanie­d by intense pain. Staying hydrated and we­ll-rested aids this delicate­ stage.

The light bleeding and vaginal itching could likely be attributed to a post-D&C infection. I would recommend you go for a gynecological examination and treatment. 

It is unlikely that you are pregnant if you were on the Depo shot and he withdrew. The brown discharge and feeling sick could be from hormonal changes or other causes, not necessarily pregnancy. Nausea can occur for many different reasons such as food poisoning or stomach problems. If you are concerned, take a pregnancy test to ease your mind. 

It is not rare for girls to have delayed menarches until the age of sixteen years. Although, having pain in the lower abdomen might be a red flag and will need to consult with any gynecologist. To have an overall reproductive health, it is essential that one gets proper diagnosis and treatment from the specialised doctors.
