Hello I previously wrote that I want to get pregnant again, meaning I wanted to have another baby. But then after reading some comments and advice from friends, I got the desire again. As a matter of fact, after childbirth, the body needs to rest plus I should give my son enough love and attention, as he was not easy to get. I thought about it. And so now today is the second day of delay, there's a test but I haven't checked yet. Two lines will be this will be an unexpected one. Is it possible that the delay is due to thrush? Or does something like this happen after childbirth? I would like to know from you.
