Chemical Pregnancy in August

Hello everyone my name is Reyna I posted on here once before but I need some new advice because I’m a little confused. I’m 27 years old and I had a chemical pregnancy in August we were trying for about 3 months and boom pregnant until it ended. It was really difficult for me especially because in January I lost my 51 year old healthy dad to brain cancer in just 3 months. Either way I decided I wanted to try again and he was all up for it. About 2 weeks passed and I got a none blinking smiley face on an ovulation test and we baby danced. Didn’t get pregnant but I also didn’t get my period. I know this happens a lot after a chemical pregnancy but it has now been 25 days late of my period and I’m not sure if this is normal anymore. My breasts started hurting 2 days ago but still no period. Not sure what to do at this point.
