Chemical pregnancy

Hi ladies, I had posted last week about the topic. Unfortunately, this was my first ever pregnancy that ended in a chemical pregnancy. I started bleeding Monday night which I thought was just my period in general. I was having crazy cramps for almost a week until the bleeding started which is unusual for my period since I usually cramp the first 24 hours after I start my period. Monday into Tuesday morning the bleeding was heavy but by Tuesday night started to get a lot lighter. Well today cramping has started and bleeding is heavier again. It feels like today is actually the first day of my period and Monday was the start of just losing the chemical. I’m not sure if that happens? I’ve talked to a few family members who have all had chemicals and said that once the bleeding started for them it was their period and it was not any longer than usual. Has anyone ever experienced bleeding before their period or bleeding that ran into their period with a chemical?
