After how long does a menstrual cycle become regular?

Hello,

There are many elements to consider in your question. I must first validate some information with you in order to answer as well as possible

Did you have irregular cycles before taking the contraceptive pill?

Are you currently experiencing other symptoms such as breast tenderness, nausea, tightness in the lower abdomen?

Are you currently in the process of conceiving?

Thank you for the clarification.

Was your cycle regular before taking the pill?

Some women use the pill to regulate their cycle

It may have been too early for a pregnancy test. Since you have no other symptoms, it is difficult to be 100% sure. I suggest that you take another test tomorrow. Normally, a few days after your expected period, the chances of detecting a positive pregnancy are higher. Since you have no particular symptoms, a pregnancy does not seem very likely, but in order to validate it, I still suggest that you take another pregnancy test. As for the regularity of your cycle, unfortunately there is nothing to do except to evaluate the probable causes with your gynecologist

Lastly, I know that in some people, the COVID-19 vaccine may have temporarily disrupted menstruation. I don't know if this could be related

It's a pleasure.

If you have any other questions, please don't hesitate
