Needing advice

So my bf and I have been trying to get pregnant... This cycle has turned out to be pretty weird. Last week my boobs were very sore and my mood swings have been out of this world. Literally cried saying "lol" 😂... Anyways I took several test which all but 1 had faint thin lines. Did the evaporator test that says if you saturate the test again in water, if it's an eval line it will go away... The line did not go away. I started what I thought was aunt Flo with really bad cramps only twice... But it was only medium/ heavy for just a few hours and spotted before that and after that... Lasting a whopping 1 1/2 days. Now nothing... Could I be pregnant or what could be going on?? I'm so confused.
