I am 3 months postpartum and had my first period 4 weeks ago. My next one was due today. For the past week I've felt weird, like I've felt like I know I'm pregnant but was just sort of waiting to find out. I've been really hungry and tired but also had really strong period pain for about a week. I think I actually ovulated 5 days later than my app said so my period should be due today but I actually think it should be due in about 5 days. I had these tests this morning but then negative on an ultra early digital?
