Adrienn 💙💙💖 • With the love of my life (4-12-13) B- (10-21-10) G- (01-19-14) A- (07-25-16) S- (08-30-18) R(08.13.19)
I'm ONLY 4dpo, but I'm unusually gassy, very crampy, Terrible backache, headaches, EXTREMELY fatigued (10 hours feels like 2) 
We BD 2 days before ovulation day of and two days after. 
Anyone else experience these kinds Of symptoms & later find out they're pregnant? 
I know it's way to early to test & implantation hasn't even happened yet probably but just curious.
