Tired, depressed and frustrated

I recently had my iud removed with hopes of conceiving again but it's already looking hopeless. The Dr removed it thinking the complications I was having would cease but, no. I'm still sick as ever and in fear that it's endometriosis. I'm a little heart broken and it's weighing heavy on me. I wanted to give my son the sibling he's been begging for and give my husband the 2nd child he desperately wants.
