My bodies playing tricks on me

A

Sooooo my cycles r pretty consistent.. either 27/28 days.... even after my D&c; it came like clock work .... I’m now on cycle day 31.... got a negative test yesterday... my boobs r swollen like when AF shows up ... I don’t know why this cycle wanted to be longer ... I’m afraid I had a chemical or something because 4 days ago I test got two negative n two what looks like Evaps... one was a cheapie n one was with blue dye so I’m just confused Nd depressed... lol I don’t know what to do anymore. Can’t afford fertility assistant nor can I get pregnant naturally n carry my baby to term . My heart is breaking into little pieces that can’t be repaired
