What's happening ?😯

So I started my period on the 14th it was unexpected becuz I had missed it for over a week now cuz I was supposed to start on the 9th 😐 in November I had a miscarriage and my boyfriend and I have been trying and I thought that maybe this time would be it becuz I was trying for like three months now and my period kept coming but on its regular time and would end within a week or so and now I've had my period for 7 days and it won't stop idk am I overreacting becuz I feel like this isn't normal😯 has anyone had this happen?
