Hi, I have been taking Lutera for 14 weeks now. Unfortunately, it's hard for me to take it at the exact same time (10pm) every day, some days I end up taking it 2-3 hours later. I've missed a pill maybe two other times. This week (two days ago) I missed a pill and it took it with the next pill the next day on time. The following day (yesterday), I had sex with my boyfriend (without a condom). Today I noticed bright red blood (not enough to be considered a period). Another important factor is I started amoxicillin 4 times a day two nights ago.

I was wondering if the blood would be an early sign of possible pregnancy or a cause of missing a pill for an entire day.
