New symptoms I’ve never had....

So I’ve been TTC since April after I stopped taking my pill with my bf of 8 years.

I recently DTD with hubby while I was in my fertile window, and now over the past 3 weeks I’ve been having cramps, SEVERE fatigue, nausea (I threw up my favorite baked ziti), and I couldn’t 💩 for a couple of days...

So other than the cramps, nausea and headaches here and there, my symptoms calmed down a little...but now I feel like my breast are super sore...I never usually feel any tenderness or soreness when it comes to my boobs around my period, so this is a pretty new symptom for me...I pretty much can’t hug someone or lay on my stomach without it hurting lol

I took a test last weekend and I got a BFN, but it a little early since my period is supposed to come next Sunday 11/11. I had spoken to my doctor about everything almost two weeks ago and she’s sending for a sonogram this week so I’m definitely crossing my fingers!!

Anyone have an opinion on what may be going on? Today is my birthday so I’m hoping for some good news this week!

***Update***

So went for me ultrasound yesterday and the technician said she didn’t see anything, but it might be too early to tell and to wait to see what my doctor says. So of course I took my disc home with me so if my results don’t come back before Monday, I have my disc with me for my doctor to quickly evaluate. Took a picture of a couple of the angles and sent them to my bestie since she’s 9.5 months and she said that one of the angles I showed her is exactly how her ultrasound looked when they didn’t see anything. She went for another ultrasound 2, 3 weeks after that and they got a heartbeat.

Crossing my fingers that I’m in the same boat, waiting to see if my period comes this weekend, but I’ve had these symptoms for almost a month so who knows 🤷🏽‍♀️....in the meantime I bought a OPK, and my bestie suggested some supplements to take in the meantime so I’m hoping for the best!!
