I have been taking Lolo for 3 months. Am I at risk of pregnancy if I don't have a period during the week I stop taking it (without hormones)?

It is possible that your body is still adjusting to the new contraceptive, which can cause the symptoms you described. However, it would be a good idea to take a pregnancy test to be sure. All the tests sold in pharmacies are good and will allow you to know if you are pregnant or not at this stage. If the test is negative, it is likely that your symptoms are related to hormonal adjustment. If it doesn't seem to stop over the next few cycles and you are very uncomfortable with it, you can always ask to go back to Linessa or another similar contraceptive. Give yourself at least 2 more cycles before making this decision. Have a nice day.
