So my husband and I have been trying to conceive baby #2. My son is 11 months old. I am still nursing him!

My question is can this be true?? I just had my period on the 8th. It was not my normal but I bled. At the end of last month I was somewhat spotting, it was more discharge with a little blood, which was faint but brownish. Like what you’d normally get at the end of a period. I guess my question is could I really be pregnant? I know I sound stupid, I’m going to re test again but wanted to get everyone’s opinions.. thanks in advance
