Every symptom but repeated BFN

So lately I've been feeling exactly how I did when I was pregnant with my daughter. Tired, sore boobs, cravings, really emotional, this morning I was making eggs for my daughter and the smell of the cooking eggs almost made me vomit. It was all I could do to finish making them. But I've taken 4 pregnancy tests over the span of two weeks and they are all negative including the one I took last night. What is going on with me?! 😭
