I have severs endometriosis and fibroids and have been unsuccessful at getting pregnant for awhile now; I have had 5 hysteroscopies, and 1 laporoscopy in the past 5 years and still no change. After the laporoscopy the endo came back worse than before. I have tried Clomid; i had a period in May then had sex the last day of my period which was 7 days long, then had another period in June 35 days later but it was short and painful and 3 days later I'm nauseated and crampy and tired, what could be wrong? is there the slightest possibility that i could be pregnant?
