Implantation bleeding or period?

So...my periods are normally heavy with clots for about 3 days into my period, then tapers off on the 4th and 5th day(my cycles last for 5 days) just to kind of put it out there. I think I made a post about 2 years ago when My husband and I was successful in getting pregnant(we had been trying for 8 years at that time)..well we miscarried about 4-6 weeks in.

Well to make a long story short. I think I'm pregnant but I don't want to say anything, or maybe I'm just crazy. So, this week I started my "period"😒 Again my cycles are always heavy with clots and are usally on time. On Monday 10/7 (my period was suppose to start on 10/6 per glow)I though my period coming because of the cramps and spotting so as usual I take a shower, insert tampon and go to work at 8am. I checked myself around 10 because normally at this time its time to change, but when I get to the restroom there was very little blood so I didn't think nothing of it I changed and kept moving. By lunch time 1:00 still the same thing and this is ongoing throughtout the day(very unusual for me). When I get home later that day around 6 or so its still the same so I changed from a tampon to a pantyliner. That night the flow picked up still light but more pinkish/redish. On 10/08 the flow was still the same very light but blood was more brownish/red this continued into wed 10/09 I think I used maybe 5 regular tampons between Tues and Wed(normally I would have to use super around this time). By thursday it was brown blood or discharge and im still having brown blood or discharge today 10/12. Has anyone had this problem? Should I test? I nervous of the outcome.
