I took a plan b in may

I took a plan b in May and had a period about three days after. (I'm pretty sure the 26th) I haven't had a period since then. Usually my cycle skips a month. So that means I should have had a period mid July.

But here I am. August 11th and no period.

I've been having all symptoms accept nausea and vomiting. I've been having tons of discharge, sore nipples, cramps during and right after intercorse. Also mild cramps for the past 5 days. Increased appetite, super tired, I did experience a random wave of nausea 2 nights ago. and peeing! Omg I've been peeing like a darn race horse!

But no spotting, and not much nausea or vomiting.

Well I took a pregnancy test this morning and it came back negative. It was kinda old though so I think I should take another one.

I've heard of something called the hook effect, where a pregnancy test (urine or blood sample) will come up as negative but when an ultrasound is done, hello baby!

I'm not sure, but I definitely want to take another test.

Let me know what you ladies think!
