The last time I had sex was the 30th of march, we didn't use protection. I am irregular with my cycle,I usually start at the beginning and end of each month.this past week I thought I was getting my period but for a whole week Rosy pink "blood"was coming out.this week my nipples are sore. What can that mean?

It can mean many things, if you were bleeding a week, most likely not pregnancy but can not be sure, no testing can be done till you miss your period for about one month,

The thing is that I wasn't bleeding it would just stain my pad with a rosy pink color

We can't know. If you period is at least two weeks late, take a pregnancy test. Or just go to the doctor and get checked out. A lot of things can mess with a woman's cycle and we can't begin to guess your situation, nor determine if you're pregnant over the internet.

Okay, then ill wait.thank you so much for your time :)
