I'm on yaz and I took it properly but one day before my cat scan I had gotten sick after I had taken my pill. I didn't know you're supposed to take another one. Two weeks later I was 4 days in my placebo pills and no period so I took two tests and both had faint positives and a hour later I got my period and it was the average AF... But I came across some info that some women on birth control will still have periods because of the placebo pills and not know they're pregnant. So could I be legit pregnant? Like what should I do? I'm on my last day of AF.
