I had my <a href="https://glowing.com/glow-fertility-program">IUI</a> on sept 30. This cycle was daily follistim injectables w/a trigger. I've had horrible constipation the past 3 days, but I'm almost certain that's from the follistim (I read that's a side effect??) but this morning I woke up and my boobs feel SO heavy. Like I'm walking around carrying bowling balls.... :-/ I've never experienced this feeling before so I'm just curious. But I'm thinking 4dpiui is a bit early to have any symptoms.... Any insight would be helpful.
