Help please🙃

Alright, so I’ve been on birth control for 5 years but I stopped taking it for personal reasons on the 14th of December. I started my period on the 12th of December and ended on the 18th. For the whole week of starting the 23rd, I had dizzy spells and a lot of fatigue. The dizzy spells is what did it to me that made me feel weird. On the 28th right when I woke up I took a pregnancy test and got a positive. The next day I went to a clinic in the evening and it came out negative. Then two days after I took another one in then morning and it was positive. Now I’ve been cramping for a day or two and they’re mild. A little back pain too. I’m also nauseous and still have those dizzy spells. And I’m super tired all the time. I’m getting a blood test tomorrow to confirm it but now I’m so afraid that I’m not pregnant because I’m cramping. I’ve been googling so much that I could be miscarrying. (Which I really hope not) it’ll be my first ever. So what do y’all think? Am I pregnant orrr? I haven’t been spotting. Just clear watery discharge. (TMI, sorry)
