Hello, Christine. It looks like there's a slight chance. That's all you need at times! I really hope you get a BFP! It would be absolutely amazing! Sending you baby dust and love. You can do this!
Cycles can be a little irregular, once you leave the pill. So, it's nothing to worry about. These things are quite common. It could still be a BFP! I really hope, for your sake, that it is! Best of luck for you! Keep us updated on how it goes!
