So ive been tryin to concieve for about 3 months with no luck

So ive been tryin to concieve for about 3 months with no luck. This month has been, a very sexual one. I checked my ovulation charts and i should have ovulated on the 10 of the month. I had sex every day leading up to ovulation and even after. On the 17 of the month i started bleeding. Not very much though and it has been spotting every day since then with the exception of yesterday and today the discharge was slightly heaveir but it quickly stoped. I am not due for a period until the 26th and even then my flow is usually heavy. The only syptoms i have had was frequent urination, but that was only for about a week after ovulation. I have been sleeping alot lately and crying, but i dont know if its just me being a very emotional person, and the fact that at first i thought i was having an early period. But i never usually cry this much. By the way my periods are normaly very regular with the exception of a day or two give or take, but it has never come weeks early. I took a hpt yesterday and it came out neg, but that might have been the outcome of testing to early and buying a meijers brand. I am scared to test again, so i wont until my period is due, that is if it doesnt show. I dont know much about implantation bleeding, infact this is the first i have heard of it, and im hoping that is what this is. Can anyone tell me of anything , past experience of any sort that could help because this waiting is driving me crazy and making me and even bigger emotional wreck. Thanks
