COULD I BE PREGNANT?

Currently at 19th day of my cycle. Had unprotected sex couple of times in the last week.

Symptoms in the last 2 weeks:

- Bloated and really gassy

- Often constipated

- Both upper and lower back pain

- Sleepy all day (it like there's weight on my eyes)

- Tired quicky

- Sometimes I feel a weight on my shoulder

- frequent urination on somedays

- Last week I noticed egg like dischage with a lining of blood - twice

- Throbbing headaches that come and go

- Really moody and emotional
