After years of infertility, it finally worked and we were pregnant...all it took was a few round of letrozole and one IUI and that was it...we were progressing nicely then it ended yesterday. I even felt the baby my vagina before we got to the hospital...now I am wondering if all these drugs and treatments really work or do they get our hopes up...My advice to everyone here...listen to your bodies and be demanding if you feel any pain. I was feeling pain on my left side continually and they told me it must be a cyst, but no one really checked. then a few days ago the painintensified and moved to the right side and that caused the miscarriage. Also watch out for UTI, though alot of pregnany women get them, it can also cause miscarriages. So we are back at the table again, and need to find out why it happened, then back on the infertility treatments we go... GOOD LUCK to you all...I am praying for more success stories
