Patient's Query

Hi doctor,

In the last month, I had unprotected sex with my boyfriend. I took contraceptive pill to be safe. I get my period on the eighth of every month, so after taking a contraceptive pill, I got my period a few days priors with clots for three days. Now I have not got my periods this month, but I m getting back pain, leg pain, and thin discharge. What should I do? My question is:

1. Should I show my family doctor to normalize my periods? And I cannot tell him about my contraceptive pill intake, so if he asks for a blood test, will it be detected?

2. Is this delay caused by contraceptive pills?

3. Is it because of fasting?

Please help.

Thanks.

Hi,

Welcome to icliniq.com.

I understand your concern.

Irregular periods can be due to the effect of contraceptive pills or due to stress or hormonal imbalance.

1. The contraceptive pill intake is not visible in the blood test. You can get your thyroid and prolactin hormone levels done after consultation with a specialist doctor.

2. Yes, the delay can be due to the contraceptive pill.

3. Fasting can lead to stress and hence delayed periods.

I hope this information will help you.

Thanks.

Hi doctor,

Thanks for the reply.

Can the family doctor help get the periods back to normal if I consult him this month?

Thanks.

Yes, these are generalized symptoms that can be present in the premenstrual period. This has nothing to worry about it. Yes, the doctor can help you if you consult him now.

Hi doctor,

Thanks for the reply.

By how many days periods could be delayed? I am getting tense. Anything to worry about? Please help.

Thanks.

Answered by Dr. Deepti Verma

Hi,

Welcome back to icliniq.com.

I understand your concern.

Periods are delayed by two to three weeks from the expected date due to the hormonal effect of the contraceptive pill. The periods are expected to come within a few days.

I hope this information will help you.

Thanks.

Patient's Query

Hi doctor,

Thanks for the reply.

I underwent a complete blood test that showed all normal, and the thyroid was in the normal range. The ultrasound and doctor said my uterus measures 11 mm, and I will get my period soon. So just for curiosity, I want to know, can pregnancy be detected in the eighth week after unprotected sex?

Thanks.

Answered by Dr. Deepti Verma

Hi,

Welcome back to icliniq.com.

I understand your concern.

The ultrasound shows no pregnancy. If you were pregnant, it would definitely show in ultrasound eight weeks after the intercourse. There is absolutely nothing to worry. The periods are delayed due to contraceptive pill.

I hope this information will help you.

Thanks.

Patient's Query

Hi doctor,

Thanks for the reply.

My family doctor has given me a tonic to take twice a day for a month. I still have not got my period, which greatly bothers me. It is not that I have not taken contraceptive pills in the past. I had taken 1.5 years back but got delayed periods, but eventually, I used to get my periods. This is the first time it has been so late. What to do? I know I am not pregnant, but it is just one and a half weeks for the next period. The doctor said if I do not get periods, he will give me a tablet to induce periods. Another question was when the doctor was doing my ultrasound, and she said my uterus measured 11 mm and I would get my period. Can ultrasound give information about periods too?

Thanks.

Answered by Dr. Deepti Verma

Hi,

Welcome back to icliniq.com.

I understand your concern.

Contraceptive pill sometimes delays periods up to one month after the expected periods. If the endometrial thickness is 11 mm, you will get the periods in a week to 10 days. Endometrial thickness of more than 10 mm in ultrasound is suggestive of premenstrual changes in the uterus. Do not worry. If no periods are in 10 days, you can take Deviry (Progesterone) 10 mg twice daily for five days to induce the periods. Kindly consult a specialist, talk with them, and take medicines with their consent.

I hope this information will help you.

Thanks.

Patient's Query

Hello doctor,

Thanks for the reply.

Is it alright if I go to the family doctor to induce periods, as he is also an expert with 22 years of experience? But the problem is I did not tell him about contraceptive intake last month when I last visited him last week. So he will be able to induce periods even if I do not tell him about the contraceptive pill, as my mom always comes with me for checkups. Please help.

Thanks.

Answered by Dr. Deepti Verma

I understand your concern.

Yes, your doctor can give you medicines to induce periods. If you are doubtful, then you can contact me for the same.

I hope this information will help you.

Thanks.

Same symptoms don't mean you have the same problem. Consult a doctor now!
