Negative pregnancy test

Hi

Ok.. I haven't had a period since the 14th of Oct. I did have sex 3 days after my period maybe. I am not on birthcontrol we were using a condom. The freaken condom came off inside of me. I took it out and some might've slipped out inside of me.

But anyways

2 weeks later my boobs were aching so bad and they continue to ache up until now.

After they first started aching ive been taking pregnancy tests every week. NEGATIVE.

I was suppose to get my period the 14th of Nov. It did not come. But i did get tiny tiny spotting of pinkish brownish blood. And since this date ive been getiing dull cramps

I took another test NEGATIVE.

I went to the urgent care for a urine and BLOOD TEST 2 weeks after my missed period. They came back negative.

I missed my period again in December took another blood test. NEGATIVE.

So the dr. Ordered an (non obstretic ultrasound) to check my.ovaries uterus.

Anyways i was waiting for the tech to mention pregnancy. Nothing so before i get off the table...

I ask " no baby" she says no.

But im so sure im pregnant. Because of the aching boobs, dull cramping, alot of cervical mucus, and the very vivid dreams!

I have 3 children i know these feelings.

I leave and nurse calls me back on the results says everything looks fine. But before that. I can see they posted my results online. Everything looks normal it says.

The last part of the bottom says my "endometrial stripe is measuring at 22mm" but uterus looks normal. The nurse did not tell me that so i call back and ask she tells me the dr says to make an appointment at the womans center for another ultrasound and they explain my ultrasound results with me then.

Has this ever happened to someone before? pregnancy symptoms. But negative blood tests and urine tests?

The ultrasound i got is it possible the baby was hiding or something. I had the ultrasound last week.

Im confused and just have a gut feeling im pregnant

I did some research "endometrial stripe " 22mm is a little high. And that is where a baby grows too. Its home until birth.

My boobs feel alot fuller now

Im just so curious again has this ever happened to anyone????
