I know we all tend to overanalyze and all of the symptoms that we have, and I've just become one of those people :) I'm 7.5 weeks pregnant after IVF and my first u/s last week showed a properly developing embryo with a strong heartbeat. Over the past few days, though, I've been feeling sharp twinges in my lower abdomen - they feel like they're right on top of my pubic bone. They just come and go; yesterday I had them what felt like all day and today morning also. Of course, I'm starting to freak out :( I know it's too early for my uterus to start stretching, so it's not that. I really hope I'm overreacting, but at the same time I'm starting to get worried, should I? :(
