Just me being a worry-wart.

I’m 3 weeks and 5 days pregnant I got my first positive 5 days before AF and I’ve been testing VERY positive since. (Like the second pink line shows up in 30 seconds). But my boobs don’t really hurt? I just get headaches and some queeziness here and there and I’m super gassy and I have white creamy discharge. AF was supposed to come in 2 days and lately I’ve been cramping.... im so scared AF will somehow still show up (EVEN THOUGH IM PREGNANT LOL). I’m just worried and need reassurance that the cramping I’m feeling is normal.. this is my rainbow baby and I really don’t want to lose another one :(
