Yes. Our 1st was a pill baby. I was taking ortho tri cyclen. Had been for like 12 years. As far as I can remember I took it correctly. And I wasn't on antibiotics. So I don't know what happened.
Our 2nd was a condom baby. We have no idea what happened there. Probably broke. But no way of knowing now!
Yes. I was on micronor. I had been on it a little over a year. I was also breastfeeding and had only had 1 period since I had my son. I'm 15 weeks and my sin is 20 months. I also didn't always take it at the exact same time.
