Early miscarriages

Hey all,

Does anyone else feel that they are able to conceive, yet unable to keep the pregnancy viable? I had an early miscarriage July 2018 after approx 5 weeks, and just experienced I guess what would be called a chemical pregnancy this week (had a positive pregnancy test on Saturday with a pretty strong line, took another test yesterday - line was certainly faded but still there, and today negative completely and then bleeding. So def no longer pregnant. Even though I was only pregnant for 4 ish days this time, I felt so emotional today. I actually had to go to a work baby shower, ugh. But overall, just hoping to get some answers soon and figure out what’s going on.
