Should i get my hopes up??

I normally have regular periods with medium to heavy flow... The last period it had was on time, but abnormal. I had very very light flow only 1 day an the other 4 days were just spotting. A little enough amount that a pantiliner did the job.

At the end of my fertile week I noticed that I had quite a bit of creamy cm, a lot more than normal...

I've been having some slight cramping in my lower stomach. I pee all the time (I do naturally anyway). Slightly constipated with a turning bloat feeling. And this morning more than other mornings my nipples are so sensitive an tingly. I checked my cm this morning and there is still alot of creamy cm.

My period is supposed to start June 10. I took a test 4 days ago an of was negative but I'm certain it was to early to tell anyway.

Could all this be signs toward pregnancy? We have been TTC for a year now, after coming off of depo. Praying for a miracle, which would give us our rainbow baby after losing our first in march 2014.

Anyone had experiences like this? And found out they were pregnant? Thoughts and comment please:) thanks in advance!
