### input:
I currently just switched from sprintec to tri sprintec to try to lighten my periods. I am sexuall active but only have been for about 2 months now. My boyfriend and I had sex last week (protected with me being on the pill and a condom) and he did not finish inside of me. Just last night it was the same thing only he did finish inside but notin was wrong with the condom and it was used properly with no tears or holes. I had brown discharge right after sex last night and that had happened before but not that soon after sex. I know there s almost no chance I could e pregnant, or atleast hope there isn t. I know it s dumb of me to probably even worry...i have been getting a lot of cramps and I got discharge the week I was suppost to ovulate but assumed the birth control would stop that. Is all of the cramping and discharge normal for just switching pills? Am I freaking out for no reason??

### output:

Hello, and I hope I can help you today. Tri-Sprintec is a birth control pill that has a traffic regimen; which means that each color pill in the package has a slightly different dose of hormones. Occasionally, women who take traffic pills may have some spotting in the first few days after each pill strength changes over the course of the month.  This may cause some slight bleeding or spotting when were not supposed to have your period. Whenever you had vaginal bleeding, regardless of the cause, usually there is some cramping that accompanies it.  Furthermore, it is not unusual to have irregular bleeding or spotting in the first 3 months of pill use. Both Sprinter and Tri-Sprintec are considered low-dose birth control pills, however there are many brands on the market that have a lower dose of estrogen than the pill you are currently taking. So you may have less irregular bleeding and spotting on a different kind of monophasic (same dose all month) birth control pill. Regarding pregnancy, the chance of your conceiving while taking birth control pills and using a condom is basically nonexistent. So I believe the symptoms you were experiencing are side effects due to the new birth control pill.  If your desire is for lighter, regular periods, a different brand of monophasic pill may work better for you with fewer side effects. I hope I was able to adequately answer questions today, and that my advice was helpful. Best wishes,
