Laura Says:
I recently found out I was pregnant. Just before I found out, I had a UTI and took Macrobid. I had a blood test at the Dr.'s office soon after I finished the prescription and my HCG levels were very high. Three days later, they were normal again, and ultrasound shows a heartbeat and everything in the right place--not ectopic. I am trying to come up with an explanation for the initial elevated HCG. My thyroid is fine. Could the Macrobid have caused the initial elevation?
