haven't started period yet......

LeAnn
My husband and I have been trying to have a baby for a little over a year now and we haven't been able to get pregnant. Last October we did have a miscarriage, but after that no luck. Up till now even, since December, his grandmother has been living with us and has been causing me a lot of stress. I'm thinking that's the reason why I haven't been able to get pregnant. However, this last cycle I really wanted to get pregnant, so I tried everything I could to not have any stress or cause fights with his grandmother. In the end, I ended up getting into a huge fight with her anyways. I automatically thought that I'm not going to get pregnant this cycle. On the day I was suppose to start my period I took the bbt test and got the highest temp I've ever gotten, though then again, I haven't been taking it constantly everyday. I was suppose to start my period last Friday and still haven't started. I'm wanting to take a pregnancy test, but my husband wants me to wait till one week of my miss period to take one. What do y'all think I should do?
