Another Miscarriage?

I’m not sure where to post this, but I could really use some advice. I also don’t have anyone else I could talk to about this, I don’t want to freak out my husband and my family doesn’t understand how this is a personal matter that shouldn’t be shared with others.

Back story: I’ve had 2 prior miscarriages, then went through fertility treatments, and had amazing twins boys. My doctor at the time said I was infertile and could never get pregnant without taking some kind of medication. My new doctor recommended I get the IUD which recked havoc on my body, and I only left in for a year and had removed in December. Going without a period wasn’t worth the issues it caused. Well since my other doctor said I couldn’t conceive on my own, I figured birth control was pointless.

Well I was a few days late this month, food has not been my friend, heartburn, and a massive consistent headache, so I decided to take a test, just in case since I was taking phentermine and would need to stop ASAP. The test was a faint positive, but the second line was visible. Well today I started to have some pretty nasty cramps on one side of my pelvis, the last time I had pain like this was when I had an ovarian cyst while pregnant with my boys. When I went to the bathroom, and I had started bleeding bright red with small clots and tissue (clots and tissue came out with urine).

I’m guessing I’m going through another miscarriage, even though it’s different from my last 2. Or maybe it’s a chemical? I honestly don’t know, but my body hurts and my head is still killing me (4 day headache).

Should I follow up with my doctor or just let my body do what it needs to do?
