Yes Hippychick - seen you on some threads but can't think which!
Anyway if it helps here we go........
Took 12 months of TTC, got pg on the 12th cycle, the one I vowed would be my last attempt. I only started TTC at 42, had a mc after getting pg after 2 attempts (!) then a month later got pg with DC1.
I temped using FF so knew when fertile days were. Luckily had a good and regular cycle. I took some of the Deanna plan on board and basically we had sex from around DAy 14 (I used to OV around day 17)until I got the temp rise. Also used OPKs as back up for extra info. I swear by temping though, found it really helpful.
Didn't take any supplements other than a multi vitamin. Made sure I lay with legs in the air for 15 mins after sex - not sure if it helped though!
Doing this for 12 months was hard going but ulitmately paid off.
I think I was fortunate that despite my age I had no fertility issues. When I told my GP I was pg and quite suprised he did say, 'well if you are ovulating and your periods are regular....what did you expect?'!!!!
HTH. I will check in again and please ask away if I can help I will.
