How long does it take for Yaz (drospirenone and ethinyl estradiol) to become effect? If I didn't take the pill during or right after my period?

To be safe, Give it about 2 weeks. There is no solid rule or absolute number of days or weeks established. Use a backup method until then. Condoms are great since they also protect against stds.

How long does it take for Yaz (drospirenone and ethinyl estradiol) to become effect (without condoms&prevent preg)? If I take the pill (for the first time) on the first day of the period

Some thoughts... If the Yaz (drospirenone and ethinyl estradiol) is not fully effective that first pack of pills (or maybe the first 2 packs), then a woman might ovulate. If she ovulates, then she is fertile around ovulation, which is about days 11-16 for a very regular 28-day cycle. But, she is not fertile (due to her period, not due to starting yaz (drospirenone and ethinyl estradiol)) when she is having her regular period of 5 days or so, when she first starts her first pack of yaz (drospirenone and ethinyl estradiol).

I'm on the Yaz (drospirenone and ethinyl estradiol) pill... When its time for my period I just spot... I want to get a normal period whilst on the pill, which pill should I take for this?

That is normal. Many women taking oral contraceptives will have light periods. That is one of the benefits of the pill. If you have any bleeding at all during the time you are taking the placebo pills, it is considered normal - even if it is only very light spotting for a short time (even less than one day). For many women the longer thay take the pill, the lighter the periods become.
Periods and Pills. It is not uncommon to not have a period while on a low estrogen dose pill like Yaz (drospirenone and ethinyl estradiol). If having a period is important, you probably need a higher estrogen dose in your pill. There are quite a few of choices. Most have 7 days, not 4, for your period. If you like the hormones from Yaz (drospirenone and ethinyl estradiol), you can switch to Yasmin, its higher dose counterpart. You need to be sure to discuss this with your doctor.

I just started my first pack of YAZ, (drospirenone and ethinyl estradiol) and today I take my first white pill... will I get my period today?

During last days. Birth control pills may have 4 or 7 pills at the end of the cycle. Once your are on those pills, you may see a menstrual period. It may not start exactly the day you start the white pills, it may not end exactly the day you start your new pack, and you may not have a menstrual period at all. Whenever you interrupt taking bcp, you are likely to experience a hormone withdrawal bleeding.
Not necessarily... Yaz (drospirenone and ethinyl estradiol) contains 24 light pink tablets and 4 white tablets. Your menstrual period will start at some point during the white tablets but not necessarily the very first day. Best wishes!

I take Yaz (drospirenone and ethinyl estradiol) for over 2 years. This month my period is very heavy. That hasn't happened since I take the pills, they always made it lighter. Is it norm?

An off month. An occasional “off” month is very common. If you have had nice light cycles for the past two years and then only one heavy one that does not seem like a big cause for concern. I would track your cycles over the next few months and see if they get back to your usual pattern.

I take Yaz (drospirenone and ethinyl estradiol) for 2.5 years. I always get my period on the day of the last (4th) inactive pill, this month I got it on the day of the 2nd. Is it normal?

Yes. Many things can cause the timing of your period to change slightly such as travel, change in sleep, change in exercise, change in diet/weight, stress, etc.
Yes. I can occur on any day of the blank week. However, if you missed any pills this cycle I would check a pregnancy test.

Do I take placebo Yaz (drospirenone and ethinyl estradiol) pill if my period came on active pills?

Continue. Continue taking your pills; you won't be sure, if what you are experiencing is just "breakthrough bleeding" and you will still come on your regular menses. You want to be sure to stay in sync when you start your new pack. If you ever stop taking bcp anywhere in the pack, while on the hormone pills, you will have a withdrawal bleeding. If the breakthrough bleeding continues, you may need to switch.
