A few weeks ago I posted about how I'm on bc and possibly from switching back and forth I have not had a period. Now I am on period week and still nothing. I'm on lo loestrin and I'm going into month 3 consecutively. I switched from Seasonique in the end of October. Has anyone ever had this problem of not getting a period? I'm super confused and starting to worry. I am making a gyn appointment for next week but am curious.
