Ladies please help

I’m so confused on what is goin on in my body. I found out on Sunday that I was pregnant couldn’t believe got a clear blue and sure enough it said pregnant. I then start testing myself through the week due to me being nervous I’ve been pregnant 5 times with 1 successful pregnancy. Back in may I had an ectopic pregnancy and had surgery. Anyway there are days that I get a positive and days that I get a negative. I’m so confused and I actually pregnant according to my last period I should be around 5 weeks. But idk any opinions? I go to the doctor this upcoming Monday.
