Conceiving after miscarriage

February 20 I started my miscarriage, finally April 21 I got af for the first time. So yesterday af was supposed to show her face again, I have tender breast but that is it. I took a cheap dollar test this morning and it came back negative. I know af can be all over the place after miscarriage, before mine I was extremely regular. I'm a little hurt and a bit jealous since a few people I know have gotten pregnant and don't deserve to have a baby ( they don't have custody of others they have or even take care of other kids) just needed to vent to others that understand my feelings. Thanks for reading ladies!
