Hi I’ve had many cycles of Clomid, ovulated in most but not fell pregnant. I have now stopped Clomid and tried my first cycle in Femara/Letrozole, I’m 9DPO and felt very nauseous all day, also been very gassy over past few days. Took a test and look like invalid. Is it that I may not be pregnant or too early to test. Any advise or support would be great.
