Pregnancy Info HOME

I am 3 days late for my period, I have had cramps that come and go sometimes there are pretty intense and I think I'm getting my period and nothing happens I've been getting this for about 3 weeks, also I'm am exhausted more than normal my habits haven't changed and I have gained some weight I can barely fit into some jeans but I really haven't noticed my eating habits change, also my beasts have gotten a bit larger the area by the nipple doesn't look darker but my nipple does a little, sometimes they feel sensitive to touch, and they feel a tad heavier, I took 2 pregnancy test both from the same box just the cheap brand in the afternoon the first one had a blue light line but it was at the top it looked nothing like the picture on the box so I was confused by that so than I took the next one a few hours later and that didn't show anything at all? Any suggestions ? I didn't think anything of being pregnant until I missed my period the second day. My husband did have a vasectomy a few yrs back but I did hear it was still possible .....
