Pregnancy Symptoms?

I'm either on Clomid or Femara- research study so I don't know which one.  Have taken both before in the 9 years we've TTC but am having completely different symptoms/side effects this time.  DH and I have had intercourse every other day this cycle- he has no male factor issues.CD5-9 I tood Clomid or FemaraCD 11 I developed a sudden and intense aversion to meat and lack of appetite- I feel hungry, but have NO desire to eat- I have never had this happen- always loved meat and loved eating.  This has continued.CD 18 brief but intense cramping in my uterus; periodic aches in my breasts began- couple times a day; heightened sense of smell that has also continued.CD 25 (yesterday) began having pain in my uterus/ovaries when I sneeze or coughIn my previous months on these meds, I have had headaches (none this month), moodiness (some this month) but thats been all. Could this all be just a result of the clomid or femara even though I never had them before when I was on them?  Could these be pregnancy related even though they started pretty early in my cycle? THANK YOU!!
