I’m now 17 dpiui and go for my beta tomorrow. I haven’t POAS because I’m terrified of another negative as this is our last IUI then we have to move on. I’ve been spotting (very faintly when I wipe) and I noticed my nipples have darkened significantly. I’m on 200 progesterone x 3 daily so I don’t know if this is why I’ve been having mixed symptoms (also fatigue, constipation and some back pain). I’m just trying to keep my hopes up has anyone had a successful cycle with these kind of symptoms?
