URGENT

TW: blood/miscarriage

So last month I was expecting my period, and so it started March 7th and I very heavily bled until March 23rd and then all my bleeding stopped out of nowhere. It was very abnormal to me as I’d never had anything like that happen to me so I was searching up all the possible causes of why that could be such as miscarriage, cysts, endometriosis, hormonal imbalance, etc etc. so yesterday I took a pregnancy test as I’m 15 days late on my period and I have been craving Chick Fil A and every sweet things, I’ve also been so groggy, nauseous and lightheaded at times and at first I was like maybe these are just PMS symptoms because I usually have stuff like that before I start my period sometimes but I have not had a headache and every single time I’m about to start my period or am on my period, I get a terrible migraine, every single time. And so I just felt like things have been a little off so I took 3 pregnancy tests all of which were positive and even the digital test said positive. I don’t know whether I had a miscarriage or I’m still pregnant and I have an upcoming OBGYN appointment soon, but I just want to know what y’all think I am going through. I’m very stressed and frustrated because I’m 18 and in college and I already have a 1 year old daughter and I’m not on birth control because every single type of birth control I’ve tried messes with my mental and physical health and I already have terrible mental health problems as it is.
