Confused

Nicole
I'm pretty confused with what is going on. In November my husband and I lost our baby at 6 weeks along, we were able to get pregnant the first month we could try again and in May we lost our daughter 4 mths along. We were told to wait 3 mths and that 3 mths I continued to bleed so my doctor did a dnc. All the placenta hadn't came out which caused the bleeding. So my body has been through a lot lately. She said wait 1 period and start trying again. So after my period I started with ovulation tests and now for the last week I have had ovulation tests showing matching or the test line darker. I also had tests a week prior with a lighter line. I don't know what is going on. I have never had this problem. Has anyone ever dealt with this? I'm lost. I don't know what is going on.
