I came off Cerazette back in November due to not being sexually active anymore, I had a normal period at the end of that month and a normal one at the end of Dec/beginning of January. However I haven't had my latest one; im 2 and a half weeks late. However, I'd like to go back on the Cerazette pill as soon as possible because I've become sexually active again. Although I don't think I'll be getting a period any time soon! Even though I had all the side effects when I was due on. I have taken 3 pregnancy tests over the past 2 weeks and they have been negative so im 100% sure I'm not pregnant and I'm blaming it on constantly being on various contraceptive pills for 3 years without breaks. What do you suggest I do? I don't want to have to wait for a period to go back on my pill.
