am i pregnant after a chemical!?

i had a chemical and was very worried to get pregnant again. i have always wanted kids, and was very excited when my boyfriend said he wants kids. i decided to temp and do opks this month. my temps looked funky but people said it was normal. i got my positive opk on the 11th and was excited. my temps looks like it spiked to a triphasic phase is it possible im pregnant. im 8dpo and since 6dpo i had cramps, 7dpo i feel sick with sensitivity to smell so much i feel like throwning up and cramps. and these headaches are killing me and im soooo tired 😭 maybe I'm pregnant again planing on getting a frer today and testing one tomorrow and one the next day fingers crossed.
