I have been taking Ortho tri-Cyclen lo before and I am switching to Spintec.  I just finished all the pills from Ortho tri-cyclen and I just finished my period.  Which pills am I supposed to take from Sprintec?  I feel like if I start the first pill, I will start the period again.
Hi, Thanks for choosing Chat Doctor. I suppose you are using a 28 days pack. If you check the pack there will be 21 pills of one color [usually blue] and 7 pills of another color [usually white]. The 21 pills of the same color are active pills and the 7 pills are sugar pills. You must begin with the active pills. You will not start the period again as long as you take the active pills. Since you have finished your period, a backup method of contraception like condoms is advisable during the first 7 days of using the pack. After that you can use them every 28 days without the need of any additional contraception. Hope I was able to help you. Thanks for using Chat Doctor. I would be happy to answer any further queries. Have a nice day.
