Repeat chemical pregnancies

Adrienne • I`m 33 and trying for my second baby. I`m also incredibly impatient! We`ve had two chemical pregnancies in 6 months.
I've recently experienced my third chemical pregnancy. Wondering if anyone else has had this experience and what their doctor advised. This was my first cycle on femara and I really thought this one would stick, but the line has grown fainter and I'm now spotting. Any advice is welcome!
