Thread: 3 months LATE and 3 NEGATIVE pregnancy tests!!!

I am 26 and the last day of my last period was 10-31-10, I have taken 3 pregnancy tests the first was the last week of december, the second was the first week of january, and then the last on just this week on 01-26-11. I have been on birth control and have always taken my pill religiously but have also been on antibiotics at least once a month for 14 days since august for a swollen lymphoid in my groin. So I know that being on antibiotics lowers the birth control effectiveness so that there is a major chance i could be pregnant. And yes i am showing some signs of pregnancy my breast are so tender, i have been nauseas for the last month i can tell i have gained a little weigh bc my jeans are no long fitting right, lower back pain, headaches, and I am constipated, which I am never constipated. I guess I am asking what I need to do! where to start to figure this out. and is it possible for me to be pregnant and have the negative tests?

my friend had the same thing.. and was pregnant.. my advice get to the doc. Find out either way.. 1 if you are pregnant.. you should be getting prenatal care... 2 if your not pregnant its not good to go that long with out getting your period! head to your GYN asap!
