2 days late, could it be??

Ok so I'm 2 days late. I've been late before like a billion times lol. The thing is I had a miscarriage back in June 2016 I was 4 months pregnant. My periods were pretty much on spot up untill now.   My husband and I gave pre seed a try during the time I was suppose to ovulate. I started having cramps and some pretty bad lower back pain about 2 weeks or so ago. And now my boobs are tender. Would it be safe to test in a couple of days?? Thanks in advance to anyone that may be able to give me some advice.
