Another BFN today after 5 months of ttc. I'm 36 and have 3 children with ExH. DH is 42 has 2 children to ExP. We would dearly love to have a child together but nothing is happening so far. I was using a contraceptive implant then the mini pill for around 4 years before we started ttc. Now I'm worried we've just left it too late and I'm kicking myself for not starting to ttc a couple of years ago.
Can secondary infertility strike after so many kids between us or are we just unlucky so far? I personally feel that I'm not ovulating (no symptoms - I've tried OPK's but the results are difficult to read) but am worried about seeing the GP. We don't want ttc to take over our lives for the sake of our existing children, so have said if it doesn't happen then that's fine, but I'm actually starting to feel really down about it now.
Sorry for rambling, I just wondered if anyone had any wise words?
