3rd mc in 8 months...

Hi, im currently going through my 3rd mc in 8 months. 1st was mmc at 13 weeks though baby stopped growing at 5+6, 2nd was natural mc at 5 or 6 weeks and now having a chemical only 1 month on from mc. As I have now had 3 I have been referred for tests. bloods to be done in 6 weeks then more bloods 12 weeks after that. I am worried about the time frame and don't really want to put ttc on hold but at same time I'm terrified its going to happen again. if there is something wrong wouldn't the mc have all been the same? each of these mc have been very different. could it just have been bad luck? if I do get pregnant again quickly without tests could they give me treatment as a precaution? my husband said ideally he'd like to wait for the testing but it's my body and if I feel ready to try sooner he'll support me (he's been amazing). Has anyone else been there? what do you advise? I feel the clock is ticking. I'm not getting younger and everyone around me is having babies. All of my besties are pregnant. this totally sucks. I'm really struggling this tine 😭
