Could I Be Pregnant??💁🏻

Rubii

So I need opinions.... My period was supposed to start the 18th but all I got was brown discharged for a day and a half, now my boobs started hurting yesterday, I feel them heavy and swollen, and I have a really strong sense of smell, and I no longer love the smell of my morning coffee😢 Before all this symptoms I had lots of nasal congestion and I mean lots like water coming out of my nose🤧 and until today I been really constipated and bloated. Thing is since I have Thyroid all my pregnancy tests come out negative🤷🏻‍♀️ With baby #1 now 2 yrs old I was already 6 months and 8 months and for curiosity I will take pregnancy test tests and they will all be negative 👎🏻 Only blood exams came positive. Please I need opinions😬🙏🏻
