Period Question

Jenna

So I am 30 days late as of today, I've had like I cant even say one day spotting just like after going pee. Wipe and there was light blood mixed with clear and next bathroom break nothing. This happened this month and last month as well. I took multiple pregnancy tests all negative. Does anybody experience this? Could I be pregnant and the test isn't catching it? I got the iud removed 6 months ago and short 4 day cycles after it was removed. No cycles at all in the 2 years I've had it in. I will book a gyno visit. Just wanted to ask other ladies their opinions.
