Took four Yasmin pills and skipped the next regimen. Will it stop unwanted pregnancy?

Hello,

Welcome to icliniq.com.

Using Yasmin pills for emergency contraception follows the Yuzpe regimen where oral contraceptive pills are used as ECP within 72 hours of last intercourse. As the first four pills have been taken by her after 30 hours of intercourse as per the regimen, so the next should be taken after 12 hours and should not be missed. The side effects can vary from mild nausea to vomiting, headache, bloating, belching, breast tenderness or even spotting. These effects are secondary to Progesterone and Estrogen in the pills.

These can be countered by taking an anti-emetic pill like Metoclopramide 10 mg, an hour before starting the regimen and also before the second dose after 12 hours. This shall prevent nausea and Progesterone side effects can be countered by increasing the water intake which can neutralize the Progesterone side effects. To help prevent you from feeling nauseous, one should take pills with food. It also helps if she would timer second dose such that she takes it just before bed. That way, she will sleep through nausea. The clotting is a known rare side effect of OC pills if OC pills are being used for years together for contraception, then predisposition for clotting increases.

But the regimen needs to be completed as per protocol to achieve the desired result. After taking the second dose, withdrawal bleeding should be expected in next 3 to 5 days and once bleeding is appreciated, it would indicate that there is endometrial shed and chances of pregnancy are minimal and she is likely to be pregnancy safe. The best would have been emergency contraceptive pills like an Ipill or Plan-B, but if it is banned in your country, Regimen is still a reliable means for emergency contraception with OC pills.

Hello,

Welcome back to icliniq.com.

If she was already on Micropil plus which is a combined oral contraceptive pill and that she has been regular and taking it daily during this cycle without any missed pills then there was no apparent requirement of taking Yasmin at all for emergency contraception as Micropil plus would have anyhow prevented any unplanned pregnancy in cases of unprotected intercourse. So if she has been taking Micropil plus even during this cycle, till yesterday without fail, then she can continue and finish the pack after missing today's pill (as she has taken Yasmin, which was not required). Once she would finish the pack, the menses shall arrive as withdrawal bleed in next 4 to 5 days and then she can start fresh pack from day 2 or 3 of her next cycle. In this case, there is no need to take the second dose (four pills) of Yasmin now.

Hello, The breast tenderness and lower abdominal heaviness with mild pain indicate start of premenstrual symptoms which is likely as she took 4 yasmin on 26th dec and exactly after 5 days the symptoms have started. It is likely that if she stops the micropill plus tabs now then in next 2-3 days she would get her withdrawal bleed /menses ,which would indicate that she is pregnancy safe. However if you are keen, then considering that last intercourse was more than 10 days back, so she can opt for a serum beta hcg test which is a blood test to rule out pregnancy as early as 8 days post intercourse. This test is conclusive and more specific than a urine pregnancy test. If the hcg levels in the test are less than 3 mIU then she is conclusively not pregnant or a negative test. This would help you allay your anxiety right away. You can get it done today itself. Also once the test comes out to be negative then these symptoms can be safely termed as withdrawal PMS symptoms and then she can stop her micropill plus for next 2 days and safely wait for her menses to arrive, which once arrive shall remove these symptoms as well.
