I did my first ivf cycle in feb and they called last week with a BFP. I'm on endometrin suppositories 3x a day. I started light spotting 2 days before I found out I was preg. I have my first sono Thursday but I can't help but be nervous because I am spotting almost all the time. Most of the time is brownish but randomly over the last few days there has been a tinge of Red. Not pink, red. I know spotting is "normal" with the suppositories but it makes me so nervous. Has anyone else experienced this?
