OT coronation st

I missed a few episodes but how did Julia and Brian make up after he told her about the snip? Is she pregnant? How? Thanks

She told him she was pregnant, he dumped her because he said it wasn't his, then he told her about the snip, she wasn't with anyone else, doctor explained they're not always 100% effective, they got back together, all happy now.

Thanks! I thought it was fool proof! Only way is to abstain then !

My fiance's youngest sibling was conceived after his mother had her tubes tied (or so she thought, one wasn't done right) and his dad had had a vasectomy, so only abstinence is foolproof!
