What should I be expecting for pregnancy symptoms? When does Implantation occur and what does it look like? I'm 6 DPO as off today. I know its REALLY early for symptoms but my lower abdomen right where my uterus is feels off, its like tingly and i have these really dull not mild at all cramps that come and go, no blood or spotting. Ive had super bad heartburn, and am so fucking tired and my back is KILLING ME! Kind of worried about it but I want to be educated in case I am. I had unprotected sex on my ovulation day, aunt flo is due in a bit less than a week *I know, shame on me* I'm aware of the consequences that come with my actions. Just want to be well educated.
