Should we try again or wait for test?

Kay

Iv just found out I’m loosing my third pregnancy at 7 weeks. I lost my second in august at 9w but baby stopped growing at 6/7 same thing happened with my 1st pregnancy. This is my third MC. I have a 2.5year old from my second pregnancy. Do we go for tests seeing as something seems to happen at 6/7 weeks? Or should we just keep trying. Thing is I don’t know how much more Mc I can take.
