TTC 1st baby for almost 8 months now

Hi im 26 years old and me n my husband have been TTC for 8 months now. I had light spotting and cramps 8 days before my period and we had intercourse the night before tht and a week before THAT. the spotting lasted just one night and then on my period due date I again eperienced some very light spotting on and off and some bleeding which lasted for a couple of hrs. I have a very heavy flow on my first day and the bleeding I had was more like something I will have on 4th day. Could I be pregnant. . I dnt want to get too excited and hopeful bt I ammmmm!!!! Please somebody tell me if they have experienced anything like that and wt could it possibly mean!!! Its still my second day of periods and there's no blood or spotting since morning
