Can I be pregnant and still have a period?

Hmm..My breast was sore since june 29 - july 4 and I though that I will get my period the next day. So it was in the afternoon of july 5 and I needed to go pee. When I wiped it down I saw a pinkish spot on the toilet paper. I was like okay this looked nothing like period, but I still put a pad. After 2 days had pasted by but there no period on the pad and my breast still sore. So I check my breast if there any changes and it did. My breast feel fuller and my areola kind a bigger looked like goosebump on it. But I decided to wait until july 11 and took the hpt and the test came out negative. So I waited until July 13 and I decided to have an intercourse with my hubby. The next day July 14, I had my period until now with mild crampand lower back pain. My breast not sore anymore but it still feel fuller with goosebump on my areola. I am so confuse right now because I read so many people question and answer online. None of the question or answer still don’t solve it. My hubby and I really wanted a baby. Can I still be pregnant eventhought I have my period?
