Symptoms of extremely early pregnancy

Emily • 25 yrs old

Hello girlies! Been trying to conceive for 2.5 weeks. Been of the pill a good 3 or 4 months. Been having intercourse every day since the day before my fertility window. My bbt was 99.30 degrees Fahrenheit. Been having slight headaches. I have been having some indigestion. My cm is a medium amount/eggwhite. AD is supposed to be here in 11 days. Feeling qweezy. The scent of any food is way too strong and I have to stop breathing through my nose just to eat. As well as unusually tired. Mid and low back aches. My cervix has had a few times where it felt crampy on one side. Mostly uncomfortable not in any way painful.

I understand that taking a PT 11days before a possible missed period is a tad too soon. However, I did take one. Negative. Now should I wait till 4 days before to test again...and also on the day of supposed period?

These sypmtoms, I've been having for almost 3 days. Also, this is our 1st time TTC. So how should I interpret these possible symptoms of early pregnancy? Especially this far from a possible missed period?

I invite any one who has conceived before 1+ times. Especially those ladies who started sort of or exactly like this with their pregnancies.

Thank you SO MUCH
