hey ladies question

so i was due to start my cycle on this wednesday april 11 but instead on Monday i had a brownish discharge for an hour so im thinking is was implantation bleeding with mild cramp then on tuesday my cycle came ( well im not sure) but it was very heavy with clots for a few hours.. this has never happen .. on Wednesday light spotting for a few hours now today i only see a little pinkish when I wipe..oh my husband and i are trying to concieve.. has this happen to anyone else and what do you think i should do?
