Biaxin & Missed Period

[GreenGrass]

For the last eight months I have been going through a lot of life changes. I graduated college, searched for a job, moved back in with my parents for four months, started a new & highly stressful job in which i work 60-70 hours per week, and decided to buy a house with my boyfriend of five years. Recently I developed a Strep Infection/Ear Infection which caused the Doctor's to put me on a Z-Pack. This was back in October (Oct. 27th to be exact). That week I was supposed to get my period on October 31 like I always do. Typically my period lasts between 3 and 4 days with it being heavy on the first day and lighter the next 2 or 3 because I switched to Kariva 2 years ago in August. I didn't get my period till Saturday and when I did get it, it only lasted about a day (almost half a day), but I did get it. I looked online to see if high stress, change, and antibiotics could affect it. In the last couple months my period has gotten shorter by a day or so, but nothing unusual. I never miss my birth control, I always take it that day and around the same time as long as I can (I never miss it, I just take it 5 hours later that usual). I also always use a condom when I have sex. The only time I don't use a condom is when I don't have one and my boyfriend always pulls out. Typically it is the second time around in an hr or so that we don't use a condom (if we run out). Well, this past month has been really stressful because of buying the house and doing my stressful job at work. I have back problems and my entire back is out of place and I have been having to go to the chiropractor a lot. I also ended up getting sick again with strep (2nd time around) about 3 weeks later. Inbetween being sick, I never really felt 100%, but I just let it go because I was so busy with work and getting everything ready to close on the house. I had to do all the house work because my boyfriend works nights and sleeps during the day. So, I was trying to get everything set-up for the house during working also. On November 19th, I ended up going back to the doctor and they diganosed me with strep (2nd time). They put me on Biaxin and told me to rest. I have been on Biaxin now for a little over two weeks and I am almost finished with the pills. My period was supposed to come on Nov. 28th or 29th and still hasn't showed up yet. I haven't had any pregnancy symptoms like spotting, breast tenderness, or sickness other than headaches that I usually get. The only time I had sex without a condom was on Sat. October 25th and the first time we used a condom and the 2nd time (which was in the same hour) he pulled out without a condom on. That Monday I started the Z-pack, is there anyway that that would have affected my period? The weekend of Sept 13th we were having sex and the condom did break and he did come inside, but I was taking my birth control religiously. In october my period came right on time and lasted the typical amount of time, so I ruled that time in Sept out because my period in october was fine. Now it is monday and I was supposed to start on Friday or Saturday and still haven't gotten it. I have always been very regular, but never been this stressed. We just moved into our house 2 sunday's ago and are in the process of moving in and refinishing the house so I haven't gotten a lot of rest. Is there a chance that I may be pregnant or is there a large possibility that between being sick & really stressed out that I had an irregular period last month and have missed it this month? I am still taking my birth control religiously and I just started my new pack yesterday...

Its hard to say what can and cannot affect your cycle.... every one is different... stress can definitely affect it (not to sure about the antibiotics and vitamins).... antibiotics can also affect the effectivness of your birth control... so there is a possibility with all the antibiotics and the pull out methods (which dont always work) that you could be pregnant.... I would just take a test to ease your mind....

I also wanted to add that I started taking a B-Complex Stress Vitamin a little over 2 weeks ago, I have never taken anything like this before, but it has helped give me more energy and let me relax a little more. Could this affect my period also?
