Hi,
I've just come here as I'm in the early stages too! Im about to get my IVF referral so have gone through the initial investigations. I'm sure it's different for others - they haven't found any reason why we can't get pregnant so at the moment it's "unexplained infertility". If they were to find a problem then I think there might be more steps to try before IVF. We have been tcc for 2 years and 3 months now.
I was referred to a consultant gynaecologist and had blood tests done in the waiting time, on day 3 and day 21 of my cycle. Partner also had semen tests done. Both tests came back fine - I ovulate and partners sperm is normal. I waited a couple of months to get an appointment.
First gynaecologist appointment: I had a chat and discussed blood test results, cycles, how long we had been trying, weight, general health and lifestyle.
Second gynaecologist visit: Hycosy scan. This was to check that my tubes were not blocked and to check for cysts. It was an internal scan using a small camera thing. I think this is standard as a first fertility investigation. I had a ovarian cyst and was told to come back for another scan in 2 months time.
Next appointment: Transvaginal ultrasound scan - I still had a cyst and looked like something called an endometrioma. Performed by a nurse and then had another appointment to see the consultant for results.
Next: Saw a gynaecologist again who advised I would need the cyst removed surgically before they could refer me for IVF, although it's unlikely the cyst was actually causing my infertility.
Next: Had a laparoscopy to remove the cyst and check if there was any more endometriosis. At the same time they did dye studies and a hysteroscoypy to check everything else looked ok (checked uterus lining, checked there were no polyps etc). Cyst is now gone and everything else looks fine.
Next step is to go back to the consultant and, hopefully, be referred for IVF! They said I just need one more blood test to get the go ahead.
It always helps to know the date of your last period or your cycle day at the appointments, they always ask. It's an emotional process so look after yourself. Also familiarise yourself with any IVF criteria for NHS referral in your area in case it does come to that. You can find out what your CCG offer here: Fertility Fairness. They may have restrictions on age, weight etc.
Good luck with your journey. I hope things work out for you!
