Definitely try clomid or femera, just make sure your doctor is doing monitored cycles.
For what it's worth, here is my advice on secondary infertility. If i had to do it all over again, i would do it totally different. I wish i knew then what i know now!
After a few rounds of clomid, try IUI. If that doesn't work after a few tries....stop and do more testing!!!!! We did not do this and it turned out to be a HUGE mistake! I just found out after 10 years of unexplained infertility that i have very high levels of NK cells. It turns out it is more common in women who have already had a baby and i also had every symptom in the book. It turns out that not all doctors test for it. It is a specialty test and has to be sent off to another lab (i believe Chicago and Boston have labs). I had to go through 4 REs before i found one who even brought it up. All of those years of clomid, IUIs, and IVF were all for nothing....with elevated NK cells we never even had a chance.
Please research and find out all you can before getting talked into IVF and other expensive treatments. Doctors use the argument that 'you got pregnant once, you should be able to again if we do enough treatments', and it's just not true! People complain that the NK cell test is too expensive (about $200) and they don't want to do it, but it's just a drop in the bucket compared to the cost of IVF.
