feeling sick

Im 2 days delay , mga mga unsual signs ako na nararamdaman na po, but i get a motorcycle ride from manila to pampanga kahapon, pagkagising ko po this morning , i had a super back ache and had a blood and nakauwi na kami kanina, and i feel severe lowe back pain, and pababa sa paa ko na na namamanhid, up to now may blood ako pero feel ko may something na gusto lumabas na maraming blood pero di makalabas, what does ir mean po? do you think po i miscarried? :((
