9dpo bfn

** to add on, ive been so tired lately. Im on wellbutrin 300mg extended release, and usually that keeps me up until 6 or 7am, and im full of energy, but lately, starting this past weekend, ive just been so tired and exhausted even my bf said "what happened to staying up till 7 or 9am like youve been doing?" But i just cant. I fell asleep on his couch yesterday, i came home from his house and i immediately went to bed, i was just so tired and groggy it was ridiculous. I couldn't even wake up this morning and get out of bed because i was so tired. And now every single muscle in my body aches, my stomach is achy/sore the most like i did a bunch of crunches, my legs are sore and my arms are sore too. Im wondering if pregnancy hormones are over powering my wellbutrin and making me tired, but im not sure about the sore muscles.

9dpo, BFN, tested with FMU :( its so discouraging seeing a negative... me and my bf literally had sex in 4 different sessions in 2 days, and he finished in me 10-12 times, on my ovulation day and the day after, im usually easy to get pregnant.... when i was 16, i got pregnant 6 days after losing my virginity... granted i didnt know, but i tested negative till i was 5 weeks along. Af is due in 5 days, i hope she stays away, i want my rainbow baby :( this is our first time trying (not the same father, ive been with this bf for 2 years, since i was 21)
