Does taking contraception pills in different times in the evening can cause pregnancy?
4 am is not evening. You should be taking them at the same time everyday. I think it’s slightly flexible like if you take them normally at 8 pm, you could take it 730-830pm BUT I wouldn’t bet my childless life on it. Read the instructions, it depends on which week you are on what you should do if you miss a pill (4 am is considered a miss) and what other forms of contraception you should be using, if any.
