I came across this thread in active convos, and reading all your experiences reminds me of my own ttc journey some years ago.
In a nutshell, I had crap cycles, no periods for months, so hard to know when to aim for. Did 14 cycles of Clomid - I got pregnant on cycle 7 but sadly had a mmc. After all the Clomid, moved onto ovulation induction using an IVF drug (forgive me, I can't remember the name of it) injections, but in smaller quantities. I had 3 cycles of this before being referred for IVF - thankfully I conceived on cycle 2 and dd1 is now 6!
When dd1 was 2, we decided to ttc for number 2. The pressure wasn't as intense and we were content with dd1 if we didn't get pregnant again. I was concerned though that it wouldn't happen without some kind of assistance, but we wouldn't be eligible for any help unless we went private which wasn't an option. Anyway, I did some research and read about Agnus Castus which you can buy from Holland and Barrett. It's sometimes referred to as 'natures Clomid'. I did some more reading up on it, worked out what dose I should take and started taking it. About 4 months later I fell pregnant with dd2 who is now 3.5. I don't know if the AC directly helped but I think it might have helped regulate my periods somewhat - they were more regular since being pregnant with dd1 but not what you would call clockwork.
I can't remember what dose etc I took, but wanted to share my experience with you because i know what's it like to be in the midst of it all, and the waiting, endless waiting is horrific. I don't think AC should be taken when on Clomid, and fingers crossed Clomid does the trick, but if you find yourselves with no more Clomid and waiting for the next stage of treatment, AC might be worth a shot.
Sincere good luck to you ladies, I totally emphasise with your individual journeys and how hard it is. We ttc for 3.5 years before having dd1 and keeping company on threads such as this helps a lot, it's often not something you can discuss with friends in RL and it can be lonely experience. Take heart that there is every chance you will go onto have a child, our journey just takes longer than most.
