Cycle or What?

So I did not get a cycle in January and was getting bummed because I new I was not pregnant and started to get on the depresses side because I have to get blood work done to figure out why I haven't conceived... Here we are in February and this week my boobs are tender and I've been crampy.. About an hour ago I went to the bathroom and whipped it was like a little blood but nothing to put a pad or even a pantie liner on, went to bathroom again and it was a little again but just a sec ago I went and it was nothing at all..... This have never happen... Has this happen to anyone else?
