have any of you became pregnant again right after having a baby? thinking we maybe pregnant again! the ol man thinks I am to cause hes getting cravings again at 3am he's like your pregnant again and he was right with my last 2. going to be tested at my 6weeks check up which will be next week. May have my mom buy me a test at Wal-Mart or dollar store! just to be sure cause idk if it's my period coming soon or if im sick from being pregnant again and kinda crappie and blotted but had a lil spotting and thats it. no more bleeding yet... I wanted to know how y'all body felt after getting pregnant one right after the other? or when y'all started again.
