Not sure what to think...

Stormy • Stormy, 29 🌻 Divorced. Baby #1 born 4/19/18 after 19 months TTC with tubal insufficiency! Baby #2 born 01/26/21 after issues with ovulation and an incompetent cervix.
So. Had a faint positive hpt on Saturday but my blood test the same day was negative (hCG was 0.1). Today is CD34 and my cycles are normally between 30-32 days. No cramps. Light pink and brown spotting. No red. I haven't tested in a couple of days but I'm now 2ish days late and I haven't tested again because I was fully expecting AF to show. Ugh. I know I need to test again but I hate wasting tests.
