[|Human|] I was on Loestrin 24 Fe for 5 months but my doctor switched me to Lo Loestrin 24 Fe because she thought I needed a lower dose, as I kept getting recurring yeast infections. The first month that I was on Lo Loestrin I got my period, very short and very light for about 2-3 days. This month I delayed my period by a week because I was going on vacation. So when it got to the placebo pill I just took a week of active pills from another pack. However, I just finished my placebo pills (inactive pills) for the month and I have not gotten my period. I only missed one pill, but took it the next day as soon as I remembered and I did not have sex that day or the next. Also, my boyfriend and I do not use condoms but he always pulls out. I took a pregnancy test and it is negative. Is there a chance that I could be pregnant??? Could this just be the result of me delaying my period for a week??
[|AI|]  Hello, Pregnancy is possible if unprotected intercourse is done around ovulation time in regular cycle. If you took Lo Holstein 24 Fe on regular basis on scheduled time, then it gives up to 99% protection. But in irregular cycle, ovulation time varies, and you also took active pills during vacation instead of placebo pill. So pregnancy chance is minimal or almost nil. Do a fresh USG pelvis to confirm or exclude pregnancy, and it also rules out underlying pathology for delayed period. Take new packet of pill if not pregnant and continue on schedule basis. Consult with your doctor always. Be well.
