Since your period is late again after taking Deviry (medroxyprogesterone), I recommend first taking a home pregnancy test if you are sexually active, just to rule that out. After that, it is best to consult your gynecologist. They can safely evaluate your current hormone levels and discuss whether to adjust your management plan or prescribe another course of medication to regulate your cycle.

It is completely understandable to feel concerned when your cycle doesn't return as expected. Deviry (medroxyprogesterone) is used to induce a withdrawal bleed, but sometimes it can result in only light spotting, especially if your uterine lining is thin. Yes, there is still a possibility of pregnancy, as medroxyprogesterone does not prevent pregnancy, and early pregnancy can also cause light spotting. I gently recommend taking a home pregnancy test to get a clear answer. If it is negative, please consult your gynecologist to evaluate other potential reasons for your missed periods, such as hormonal imbalances.

What you are experiencing is very common and is likely the beginning of your withdrawal bleed, which acts as your period after taking Deviry (medroxyprogesterone). When you stop this medication, your hormone levels drop, triggering your uterine lining to shed. This often starts as light brown spotting, accompanied by mild stomach and back discomfort as your uterus contracts. This shows the medication is working as intended. However, if your pain becomes severe, or if the spotting does not progress to a normal flow within a few days, please contact your doctor.

After finishing medroxyprogesterone acetate (Deviry), a withdrawal bleed usually occurs within 3 to 10 days, but a longer delay can happen. Since your pregnancy tests are negative, the lack of a period may be due to low estrogen levels, temporary hormonal fluctuations, or stress. I recommend consulting your gynecologist. They can perform a simple evaluation, check your hormone levels, or do an ultrasound to understand why your cycle is paused and safely guide you on the next steps to restore your period.

Since you had a period on November 14 after having sex on October 29, pregnancy from that event is highly unlikely. Your delayed December period may be due to a simple hormonal imbalance. Bleeding typically occurs a few days after completing Deviry (medroxyprogesterone). Please do not start Diane-35 (cyproterone/ethinylestradiol) on your own to induce a period, as this requires medical supervision. I warmly suggest taking a home pregnancy test to be absolutely sure, and then consulting your doctor to safely guide your next steps.

Taking Deviry (medroxyprogesterone) will not cause a false-positive pregnancy test. Pregnancy tests measure a hormone called hCG, which is completely different from the hormone in Deviry. Regarding your second question, Deviry does not directly help you get pregnant or stimulate ovulation; instead, it is used to regulate your menstrual cycle. While having a regular cycle is helpful for tracking your fertile window, Deviry itself is not a fertility treatment. If you are hoping to conceive, I warmly encourage you to discuss this with your doctor to find the best plan for your journey.
