Curious 🤔

Been trying for baby #2 I've had sex literally everyday all this month, and no signs of a positive test yet, maybe still to early. But my boobs are slowly becoming tender in some places. The entire boob isn't sore, but slowly more areas are becoming more tender. I've asked my bf how hard did u suck on them? He said not really that hard, and there are no marks of hickies.

Could this be an early sign, and the tests aren't quite ready to detect it yet? 🤔
