When I first began taking the pill I was taking the combined Microgynon pill for around three months. However, I then changed onto the mini pill Cerazette for around three months. I didn't take well to this pill and spoke to the doctor who then prescribed me back onto the Microgynon. However, it has been over 10days since I took my last Cerazette pill and I haven't had a period. I had spotting for a day but was unsure as to whether this was my period. According to the instructions I cannot being taking the Microgynon pill until the first day of my period. If I were to begin taking before I have had a period would it still protect me again pregnancy?
So long as you're taking birth control continuously, then you should be fine. If you stopped taking it at any time then you could potentially get pregnant in that interim but so long as it was uninterrupted, you're okay. Does that help?
