Sorry for your losses. Multiple MC is referred to as sub-fertility, not infertility. Not that is makes any difference- you still don't have a baby at the end! Generally, the decision for IVF is on the advice of a specialist after thorough tests- not just to try something else. Can I ask how old you are?
You and partner need a thorough gynae/fertility check to rule out causes for the MC's and whether IVF would even help.
If you are in the UK, the 1st step is speaking to your GP asking for referral to a fertility specialist. GP would normally do a day 21 blood test on you, to check if you ovulate.
Pre-covid, I worked abroad several months of each year and paid to see a specialist there. I'd been ignored by my UK GP for years, day 21 blood test was normal, nothing more done, refused specialist referral despite TTC 4yrs with no pregnancy! I'm telling you, because I'm not 100% sure what UK GP's normally do and what tests the infertility specialist normally do. These are the things we had done:
- STI checks for us both
- Hycosy on me which in an ultasound with a specialist dye foam in the uterus to visualise the shape of the uterus and check the tubes are clear. HSG is very similar, but uses radiation under and X-ray.
- DH had a semen analysis
- I had hormonal blood tests, thyroid, glucose and I think regular checks for anaemia, liver, kidney bloods tests etc
- Height/weight check on me, plus a thorough medical/gynae/surgical history on us both
I'd also suggest checking whether IVF is covered in your county/area. Some counties cover no NHS rounds, others have some with certain criteria. Only 1 round after 40, no previous children, non-smokers, BMI less than 30 are just some of the criteria that some areas put on NHS IVF. Check the rules in your area so you are at least aware before you see the GP.
Sorry this is long, but these are the things I'd wished I'd known 10yrs ago when I started my TTC journey. Unfortunately, I've had 3 MCs, 2 rounds of IVF and no successful pregnancy.
