My early pregnancy symptoms were at 8DPO, I got heartburn at night. Happened for four straight nights which is very unusual for me. At 10DPO, I got a BFN. 11DPO, same thing. My BFP came on 12DPO. The heartburn went away pretty quickly but the nausea took its place. I also had some cramping. Why I thought this cycle was different was because I cramped for half an hour at 8DPO and I never cramp until I'm in the throws of AF.
My boobs didn't start to get sore until week 6. STILL cramping at 8 weeks and for the most part, it feels EXACTLY like AF cramps. The cramps are due to the uterus stretching.
So, at the time of my BFP, I had:
heartburn
I did
not have:
sore boobs
peeing a lot
nausea
moodiness
cravings
thirsty
gas
None of those symptoms started until the 6 week mark and they are getting progressively more serious as time goes on.
I found FRER (First Response) gave me the best line out of the three different brands I used. The digital came up + at 12DPO also. The $ store test was also positive (faint) but it was the FRER that came up quickest and left me with no doubt whatsoever.
Hope that helps girl.
