Devastated

My heart is absolutely broken. I’ve lost children before (miscarriages) and since the last one I have had FIVE surgeries to correct the damage and be able to have a child. After the 5th one a year ago, the doctors said I was completely fine now and will be able to carry a pregnancy full term. Well I hadn’t really tried for a year. I ended up starting to feel really off the last couple days of June. I missed my period on July 4th. Between those days, I was getting faint positive tests. But once it hit around July 11th, they started getting lighter and eventually almost completely went away. I ended up going to the doctor to get a blood test done. I was supposed to be 6 weeks and 2 days that day. The next day (yesterday) they called and said that my test was positive but my levels were only in the 50s. They said they should be well into the 500s by this point, then they said “just wait a little bit and see if you start bleeding” like wtf??? They don’t seem like they wanna help maybe stop this from happening at all. My emotions are so out of wack that I just wanna cry and yell at the same time😢😢😒 I also feel completely alone in this.. I haven’t told the father because well, why should I? Apparently there won’t be any baby so why even upset him?😓
