2 mc's and doctor not helping!

Hi, it's comforting, (yet depressing at the same time) to see so many people with the same frustration of TTC. My problem isn't TTC but holding a pregnancy. I've always been a let's not plan and see what happens kind of person in life, and it worked well for us my first pregnancy, no problems whatsoever, well other than the unplanned c-section. I got pregnant two years later, only to miscarry a few weeks later. My doctor said MC happen to 1 in 4 people so not to stress about it (easy for her to say, when I had already told my son he was going to be a big brother). We started trying for real after that and go a BFP in April, this time I held the pregnancy for one more week than the last time, but lost it again. I thought the silver lining was that my doctor would take me seriously this time, but she still doesn't seem at all concerned. I really feel like something is off and want to get to the bottom of why. I feel like my life is on hold, because I'm always making plans for the upcoming months assuming I will be pregnant and then I'm not etc... I started showing right away this last time and actually went out and bought lots of cute summer dresses for my cute summer belly... Anyone have any ideas for making the doctor take me seriously? I live in Canada, so it's free to see the doctor as much as you like and get almost any testing you need, so I'm thinking about making appointment after appointment til she just gets sick of me?
