I got pregnant naturally and within 2 months of not using birth control with an FSH of 12.4..and I was 39.
I also got pregnant the first time trying after my dd was born..this time I was going on 41 and my FSH was around 15. (The pregnancy ended in miscarriage due to a chromosomal abnormality which wasn't uncommon for my age.)
You're fine (!), but the best advice I can give you is to try and relax! That was absolutely the key to both my quick pregnancies - the first time I wasn't trying (and I was in a happy, relaxed frame of mind); the second time I tried but I didn't think it would work the first time anyway so I wasn't stressed.
Good luck!
My fsh was 12.4 and we did injectible medications and timed intercourse. I am now 29w2d pg. I will be 37 next month. I dont think your level is too high, I have heard of other with even higher levels getting pg. Fsh can fluctuate and just that alone doesnt give a good picture of ovarian reserve. Good luck.
