I just joined here, because I can't find that much information on the internet and I thought maybe someone here had experienced this or knows anything about it.

I've been on Yaz for almost a year now. It has made my period absolutely consistent, making me start my period on the last Saturday of the pack at about 10 am. Seriously, it's even down to the same time.

Today was the last Saturday of the pack, and I haven't even experienced any cramps, and it's almost 7:30 pm here. I haven't started, and it's really weird.

I was sick for a good week with bronchitis and pharyngitis, and was prescribed antibiotics that I took for a solid week. I know that antibiotics can lower the effectiveness of BC, but I don't have sex, so that's not a worry. I was just wondering if antibiotics could also make your period late, even when on the pill. That's really the only thing I could think of, besides that I haven't eaten that much lately, as I've been sick. But, I was under the impression that being on birth control would cause my period to come regularly even under those factors that generally cause missed periods when not on BC.

Has anyone experienced their period being late while on BC? Thanks.

Yep I havve been late. I am have never started the same day. I've been a whole week late so I was actually bleeding week 1 into my new pack. It's not a common thing to be that late, Being a week late only happened about 5times in my life and I've been on them for over 15 years.

I rarely start bleeding on the first sugar pill. Being sick can throw yout body off and that can lead to not so regular periods.

Thanks for replying.

I guess it just seems so weird to me because for a whole year now, my period has come RIGHT on time, every single month, and today, it's just..not.

I was on antibiotics and cough syrup, but I really didn't think that would push my period back, because I've been on antibiotics before and still got my period on time.

It's just weird to me. haha.

I think that is a definite possibility! I'm sure the antibiotics can do that. My period sometimes comes a day later or so, but it's usually close to the same time. I think mine varies every now and then because occasionally (like for a vacation) I will skip a period and skip the placebo pills.

When we are sick, our level of stress goes up, and stress can certainly make your period late. That said, it is perfectly normal to sometimes skip a period all together for no real reason. It is totally fine, and healthy. If you skip two periods in a row, mention it to your doctor, but if you are not having sex, there is almost certainly nothing to worry about.

If you miss more than 3 periods in a row you need to contact your OBGYN. Women who are athletes, ballerina's, gymnast's or others that eat poorly to keep their weight down are at a risk for amenorrhea. Physical activity, excessive weight loss, use of antidepressants or tranquilizers in general can delay a period for 2 months. PCOS can be a cause too for a period not coming down. If it does not come down by the 3rd month I'd would definitely make and appointment to see your doctor.

Amenorrhea is not a serious condition but the underlying factors that cause it can end up eventually being serious.
