BUT...since last week I have tingly nipples and gas with bloatin and this week started having stretching pain in my righr pelvic area. On the 20th I tested again that morning and bfn. Then the same day had cramps and spottoed brown and pink just once. I had a feeling since ive been super bitchy today and this is what popped up. Could I be pregnant so soon? Whats yall experience
