Trying to conceive. Test fir mg husband?

My married life is 3.5yrs. i conceived naturally after trying for 4 months last Jan but had a medical abortion in June due to weak cervix.. Again started to try from december but hav not conceived in total 6cycles now. Yesterday i got my period. But before that i had done kit test which was negative but after 5 min i saw a very faint line. I did one test 3days ago but and kidney stone problem. All tests for me were normal. Do we need any test fir mg husband?? I have put on weight also. I have bad metabolism so even after walking 5km per day i am unable to lose weight. I avoid heavy exercises because i am really scared that if i conceive it might create problem. And my diet is really 2 controlled one.. kindly suggest how can we conceive faster. I had to leave my job due to high risk pregnancy last year. So m even scared for my career now.. please help with my problem.
