I’m TTC#3 and it’s taken well over a year every time. The first time I went to my GP before the year mark and I had testing because I had irregular cycles. I wasn’t ovulating on my own and was given clomid.
The second time I went around the year mark and was diagnosed with PCOS and given metformin.
I’ve been a few times this time around as I’ve had 3 early losses and have been trying since May 2018. They’ve run some basic blood tests and put me back on metformin but won’t really do much else as I already have two children. The last GP I saw said it was all just bad luck as my body has had two successful pregnancies. I’m planning to go back soon and push for more testing. I keep putting it off though as I feel guilty for using the national health service (free at the point of use and tax payer funded) when I already have two children.
The guidelines in the UK are that they’ll start test after a year if you’re under 35, 6 months over 35 or when you start trying it over 40. If you have concerns about your cycle etc they might do it earlier though. Depends on the GP. The funding for treatments varies depending on area.
This is the first month that I got my period and then cried from dissapointment.
Cant wait to see if they get darker over the next few days !
