Me and my b/f had sex three days before my period while I had my period and after my period my cycle is usually 28 days but I usually have my period about 5-6 days is there that chance I can be pregnant? I already have a child and when I found out I was pregnant for him and went to my obs and they asked me when my last period was I told them and they told me that was inpossible because of my conception date... so now I have thoughts on if I could be pregnant.

While your sexual activity falls into days when you are less likely to be fertile, the truth is that women have become pregnant when outside the expected window of fertility.

My child was conceived during a "safe" period in the fertility window using birth control that has a 5% failure rate with proper use. Oops. Babies happen sometimes with sex, even when you "know what you are doing"...

You might not be... your window of fertility seems to favor less likely, but there is no guarantee outside of abstinence.
