Pregnant??

Hello, I have major questions!!!! So I was breastfeeding my son for awhile. He was 22 months and I would have kept going but he tragically passed away end of November! I made sure I wasn’t producing any more milk and it got to the point where I wasn’t. My boobs even went back down in size. I had my period a week early and now im lactating again after noticing my boobs swelling and hurting. Along with other symptoms I just feel pregnant. Would you say that’s a major pregnancy sign? Or just left over milk from not breastfeeding even though I dried up? Two early to test though! Thank you in advance🤞🏽💕
