if the pregnancy test can back negative then most likely you arent pregnant....... if you are worried, we can not be of much help bc we are not doctors....... you need a check up......... maybe its just weight gain...... it can mess up with your system like that.... or it is weight loss eeither one can do that.
I too have just went thru what you decribe. i had my tubes tied 19 yrs ago but i have been wanting a nother child since then, i started spotting sun the 29th and then by wen the 2nd i had a heavy period for 2 days then by sat i was spotting again, then sun i was off. My periods are usually pretty consistent, but i can't remember but i don't think i had one in Nov and then this, i took a home test and it came back neg, but i feel like i am pregnate, my belly is getting bigger and i have some of the signs, the back pain, the cramping, i dont know what i should do
Could be an off-period or your period might be starting.
If you continue to have symptoms that concern you, please see your doctor.
