Here's my TTC timeline
Jan 2011: start TTC. Nothing happens for 3 years (we were quite happy biding our time)
Jan 2014: OH has sperm analysis - turns out his sperm is basically rubbish - 1.5m count, 0% normal morphology, 15% motility. Told we'll never conceive naturally and IVF with ICSI is our only option.
August 2014: get IVF referral
Sept 2014: natural BFP - MC at 6 weeks
Jan 2015: IVF #1 - BFN
June 2015: Natural BFP - chemical
August 2015: IVF #2 - BFP - chemical
December 2015: Natural BFP - ectopic. Delays our planned IVF #3 in Jan 2016
Jan 2016: decide to give up trying naturally so as to avoid another MC/ectopic delaying IVF again
Feb 2016: accidental natural BFP. Am now 22 weeks pregnant and everything looks absolutely fine with baby.
I can't believe that I've turned out to be one of those miracle stories that you only ever read about on the Internet. I genuinely still can't understand how we got pregnant naturally, having been told more than once that we would not conceive naturally. We were even advised to consider a sperm donor!
OH started taking Proxeed for Men in Jan 2015, and I started taking Proxeed for Women in July 2015. OH also started on high strength vitamin C in Dec 2015. We both drank less (although didn't cut it out completely). We'll never know if any of this made a difference, but it may well of done.
Good luck, and never ever give up.
