Could I be pregnant?

I need some help ladies.

I feel like I’m possibly pregnant but there’s an odd twist. I’ve taken test that have all said negative, I had a light, shorter than usual period this cycle and I’m having some symptoms that are making me lose my mind. As you can see my period in feb and March were longer than my April one but I also had no heavy days in April and started a day later than I was supposed to and with no spotting like I usually get the two days leading up to my period. According to glow I was supposed to ovulate like Wednesday but they keep changing my date because all my opks are negative.

I’ve been crazy tired lately, sore/swollen boobs, increased amount of CM, backache, random dizzy spells that last even after I’ve eaten. Last week I had a random day where I was nauseous and couldn’t keep anything down but that’s gone away, today I got random period type cramps and was bloated for about an hour then they both went away.

I’m just wondering if anyone has had this happened and turned out to be pregnant. I would technically be considered 6 weeks but all these hpt are negative.
