HELP!!!!!!!!

TMI PICTURE BELOW !

So I have very regular periods and my cycles last 28 days. Me and my bf baby danced on the 18th and was expected to ovulate on the 20th or 21st. I had not felt any symptoms till the 1st June when I got back pain and achy boobs so I took a hpt on the 3rd got a bfn , took on the 4th bfn. On the 5th AF was due and she was no where to be seen just cramping and achy boobs feeling nauseous and tired. She was late I told my self no tests till Friday. On the morning of the 6th I checked my cervix with my mirror and a gust of blood came I thought oh it’s AF however this AF has been so weird.

It’s lighter and it’s brown with tissue particles , it’s not bright red like my normal periods and heavy which feels my whole pad , it’s just light pink brown with tissues particles coming out here and there . I have never had this before. I still have mild achy boobs , and faint cramping here and there. The blood is similar to when my period is ending but it just started ! Can anyone please tell me what’s going on 😥

Please please comment.
