Short cycles and early ovulation

Does anyone have short cycles (21-23) days and also ovulate early? We have been trying for over a year and have had 4 chemicals. I have been typically waiting til i was about a week out from my cycles til i tested with opks but I decided to do it differently since I do have irregular periods and it seems I may have gotten a positive opk on cycle day 7? Is it even possible to ovulate 2 days after my period ended? Thanks in advance! Pictures are of my test the last two days, bottom three was from cycle day 7 and the top 3 are from today cycle day 8
