worried...

Starting to worry a little bit. All day today I've been having cramping. They feel like strong period cramps. They last maybe about a minute then goes away. No discharge other than what seems to be normal. I've had to urinate a lot and after every cramp it feels like I have to poop (TMI, I know sorry). I've been having frequent soft BM since yesterday. Last week the doctor put me on bed rest due to spotting and cramping. She said my cervix is still closed and thick, and the baby is still growin great. Any ideas? Sorry FTM and worried.
