trouble ttc with new partner? advice?

Hi hope its ok to most this here....any advice or ideas would be great...
I have 3 children from when I was with my ex husband. My daughter took 5 mths tc my sons took 2 and 1 months tc. Before my daughter I had 2 pregnancies concieved in 1st month. My new partner and I have been ttc since Nov last year with no luck even though the first 4-5 mths I used opk tests which turned positive when I ovulated. I am 30 my partner is 32 {he has not ttc previously} we are both healthy non smokers, my cycles vary between 27 and 30 days....Should I be worried??? who do I see about this and do you think I need to or am just worrying over nothing??? thanks

Hi

I had DS without trying when I was with my ex-hubby, and then met DP and after 9 months of trying with no luck, someone suggested to me that there may be a problem (our family doesnt really have a problem concieving, but DPs mum did, so it was suggested maybe something had been passed down) so we both got tests done, and DP was found to have a terrible Sperm concentration AND morphology (how 'healthy' they look), we decided straight away to go to fertility specialists as it was clear we werent going to have a baby without any help.

The specialist put DP on a 3 month course of a supplement called Menevit (male version of Elevit) but at the end of that bottle there'd been no change, and we were told it was time to go on the IVF waiting list as he didnt even have enough to try AI (Artificial Insemination, my baby brain seems to have deleted the human equivalent from my vocab!) DP asked for another 3 months worth of Menevit and went home and did some research and found a herbal supplement called Herbal Y Extreme for men, contains a herb known as Horny Goat Weed, 7 weeks later we found out that we had concieved our daughter without any further help! He fully credits Menevit and the goat weed to being the means to him finally being a dad, and now that we know what can work, we will be trying it much sooner next time around (just have to wait for the dust to settle from this ones arrival and start convincing him another one would be just as good as first time around haha)

Good luck!
