Is this in my head?

Jessica • Still trying for our 🌈 baby, 4 mc ❤️
Miscarried in naturally Oct, took until mid Dec to get levels back to 0. Had heavy bleeding 12/9, while still positive, but never AF... anyways, boobs are sore as hell and feel like I've been hit with the flu. Took a test today to see what's up. Is there a second line? Help/please tell me I'm not insane!!
