Help?

I had a MC march of 2016 and then an ectopic pregnancy with the removal of my right tube in June of 2016. I got the nexplanon in my arm July of 2016 to give my body a rest and then removed it may 3 2017 so we could start trying. I just had my fourth cycle since we started trying. My doctor said if I don't conceive within 6 months of trying then I need to be seen again. I don't want to be seen again unless it's because I've conceived. I have two boys from my previous relationship and my husband had a daughter from his previous relationship but we have none together besides the two we lost last year. :( We've both stopped having anything alcoholic to drink, I stopped all pregnancy harming medications, he stopped smoking and I started taking prenatal and low dosage of aspirin. Any tips, advice or anything to help me? I'm expected to get aunt flow in a little over a week but I pray it doesn't show and I get my BFPT please help!!
