Question: Spotting Eight Days before Scheduled Period?

 teenager123 - Mon Jun 07, 2010 9:48 pm

I am on yasmin birth control. I was on antiobiotics for a cold for about three weeks. During those three weeks I had to take plan b twice. I went on to have my period at its normal time, in fact, it was shorter than usual. I waited about three weeks after taking antiobiotics (assuming they were out of my system by then) and about a week into a new pack of yasmin to have sex without a condom. I also did not miss any pills during this time but was four hours late one night. Eight days before I'm supposed to have my next period, I started spotting for one day so far. What does this mean in regard to pregnancy and did the antiobiotics or Plan B cause this?

User avatar Hello,
Whenever you take emergency contraceptive pills (plan B) you risk messing up your cycle because of the strong hormones involved. I suspect this is all that is going on. By the way, it has been shown that most antibiotics do not affect birth control use. Rifampin is the exception, used mostly in TB; not in routine infections.

Taking antibiotics will not help a cold anyway because in almost all cases these are caused by viruses and antibiotics do not kill viruses. It is best to only use antibiotics for bacterial infections, actually diagnosed, such as strep infection - beyond the typical and common cold or flu.

Best wishes

Sorry to carry on with this conversation but I did eventually end up getting my period which ended about 2 weeks ago. About a week into my new pack of pills I began spotting again. However, this spotting is heavier than last time and has lasted about a week already. I don't start my next period for about 10-14 days. Is there a reason for this spotting that I should be concerned about? Could it still be due to the Plan B I took about 2-3 months ago?
