<s>[INST] Good day! I am taking ovamit now for 3 months, during those months i am experiencing delay in my menstruation. On my first month i was delay 7 days, on the second I was delay 1 day and now i am delay for 3 days. Is this normal? Before I have a 28 or 30 days cycle but now, it seems that I had it irregular. I already take a pregnancy test but the result is negative. Is the delay on my cycle normal? [/INST] Hello,Thanks for visiting healthcaremagic,Taking the oral contraceptive pills alter  the hormonal level slightly which induces irregular menstration cycle. So need not worry about this. </s>
