Af due in 2 days tested this morning

So I tested this morning and got this positive test, last month a had a chemical and before that I had a miscarriage at 14 weeks- and before that a chemical. My period is due in 2 days, I’ve taken other test and they are getting darker but with my cramping right now I’m so worried I’m having another chemical 😔 (I don’t know where to post this so please tell me if it’s in the wrong group)
