I am 29 years old, have had two children which required medication to conceive. I am 5 foot 3 and 174lbs. My last period was April 16th 2015. On May 31st I had extreme pain in my lower abdomen which felt similar to contractions. I was expecting it to be my period, but after the pain left there was no sign of a period. Since that time I have had slight cramping, frequent urination, fatigue, slight constipation, a episodes of dizziness and nausea. I have taken a home pregnancy test which was negative and went the doctor for a blood test, since I could not get positives test with either of my children until I was 7-9 weeks pregnant. The doctor just wants to give me progesterone to see if it will induce a period. Should I be concerned by anything else?
