36 trying to conceive 2 years after ectopic any advice

Crystal

I'm 36 I had an ectopic at 34 we've been ttc since with no luck. I have had blood work done nothing wrong. hubby has 13 year old twins not to mention the time he got me pregnant 2 years ago so what could be the problem and does anyone have any suggestions to help us conceive. I've tried pressed prenatal vitamins evening primrose oil baby aspirin laying on back with hips up. everything I can think of please help this is getting very heartbreaking
