Overweight and TTC

My boyfriend and I are trying to conceive.  I am 19 going to be 20 in less than 10 days so I know I am around my prime as far as fertility goes however I keep seeing that being overweight is an obstacle for any woman trying to conceive.  I am 158 lbs and 5'5 so my bmi is 26.3 which is only 1.3 away from a normal weight bmi.  I walk at least 10,000 steps no less than 4 days a week and I eat pretty healthy and I don't have a lot of belly fat so I'd say i am healthy but my question is will this be a problem for my boyfriend and I trying to conceive?  I also have regular periods if that helps any.
