My last pregnancy I had so many complications to the point where they told me I couldn’t have kids anymore and if I did I could be having miscarriages ... I haven’t had my period since I was pregnant 2 years ago. I started what I thought was period but it’s been wired. The 8th I started cramping and feeling sick. The 11th I woke up and my underwear had this brown like discharge kinda like old blood , then later on in the afternoon I went to the bathroom and I had a thick blob of blood it’s was gooey . I didn’t think anything of it I thought it was blood clots .. but every time I check my pad it doesn’t have blood just old dried up blood like if I was ending my period. I had sex with my bf 2 months ago & we used protection , I highly doubt I’m pregnant.. I even took a pregnancy test and I don’t see anything. Any advice ?

I am going to the doctors today to get checked out but I wanna know if anyone been through this .
