I know I don't post a lot - but I do read a lot of the posts. Anyway - I just read your post about jealousy and pregnancy - so I want to share another old lady's story.
I am currently 38 years old and we spent 11 months and 3 miscarriages to get this baby (I am 7 months pregnant).
I was ovulating like clock work every month - and I was getting a 12-day ultra-sound - so we knew they were nice size and my lining was good - but I still lost 3! Sometimes it just takes time.
Anyway - I started taking extra follic acid (800 mcg over a prescription pre-natal) DHEA (75 mg a day) and Royal Jelly. The DHEA is supposed to really help because it is a naturally occuring hormone in your body that you start losing in your early thirties! Finally, after my 3rd miscarriage I had a D & C - I really think that the cleaning out really helped me - I got pregnant and kept it next cycle!
Keep your chin up and keep trying! Us old ladies can have babies too! If your doctor is not doing 3 day bloodwork and 12 day ultrasounds - ask them to! It can really help with timing!
If you have any questions - page me! But don't lose hope - you are a great person and you just need to get passed the stress and hard times!
