Pregnancy

Long story 😩 I go by Glows calendar for my cycle. The last four cycles my period has came a day later then Glows calendar. My last cycle it came a day early. I normally have a lot of blood clots. This cycle there were really none (a few very very small). Lasted 3 days. My cycle is normally 3 to 4 days. I even mentioned to a friend how this cycle was the smoothest cycle ever went through. I normally get sick and get headaches. I was expecting a BFP because I "did the do" during my fertile week. And I felt nauseous up until my period started. All of my pregnancy test came out negative. And before I started my period I felt pregnant. Since I started my period And I seen the small clots, I figure... I'm not pregnant. But today my nipples are sensitive and they're never sensitive unless I'm pregnant. Even tho I'm not pregnant I still feel pregnant craving fatigued nauseous. I felt my nipples and I thought "oh my gosh no way". Should I test again? I don't want to get my hopes up because clearly started my period. (oh so I think). What do you think? I'm trying not to get too excited 😩
