Clomid question!

Jamie
This is my 2nd round of clomid I take it day 3-7. I was prescribed provera to bring on a period so when it came I started clomid well its day 5 of taking it but my period ended yesterday. It was a wierd period it wasn't heavy at all. Usually when I take provera I get horrible cramps and its super heavy. I talked to my dr but she dosnt seem too concerned she told me to keep taking them. Im just nervous about being pregnant and taking clomid. Has this happened to anyone?
