Had tubal reversal in September 2015. Completed 5 day cycle of Clomid fertility med on April 10,2016. HCG level is less than 5 yesterday. Dr said too soon to tell. Need to retest in 4 weeks. Having every symptom of pregnancy. Normally weigh between 123-126. Right now I weigh 144. Only time in my life I weighed that much I was pregnant with my son. Emotional, enlarged aore breasts with veins across chest, I look 6 months pregnant, tired & moody all the time, crying for no reason randomly, irregular almost absent menstrual cycles for the last 3 months, about 40 negative home pregnancy tests. Home pregnancy & urine tests never worked on me when I was pregnant with my son. I was 2 1/2 months pregnant with my son when blood test showed positive for pregnancy. Could I be pregnant now or is there a serious medical condition that I should be concerned with?
