You're going to get a lot of responses... because, yeah. This is really common.
Hugs! Because that doesn't make it easier!
Docs won't even send you to a specialist until after your 3rd miscarriage in a row. Which you're at IF (and I hate to add this) you were at least 7-8 weeks pregnant. If you've been having chemical pregnancies (crossing fingers for you this is the case!), then you can take a deep breath. Most women have between 4-6 chemical pregnancies a year if they're sexually active and not using protection. The DNA doesn't zipper right in most cases, and you have a normal to heavy period a few days to a week or two late. Docs don't count these in the 3 in a row... because there's everything RIGHT happening, instead of something wrong. ((You body and the ovum/embryo do constant checks to make sure the DNA has zippered and combined correctly. These mistakes are caught during the first 6 weeks and include things like not having any bones, or acid for blood. The body or embryo goes "Yikes!" -to simplfy a dyslexic looking combo of chemical reactions- and hits the self destruct button. NORMAL, NATURAL, AND WANTED. If this is the case... then there is NOTHING wrong. It's still painful, but it's not a problem to be fixed. If anything, it's a very very good sign of things to come!
If it's not...
I don't even know how many babies I lost in my late 1st & early 2nd trimester. Which might be hard to imagine at 3 in, but that happens. The most painful was the little girl who was 6 going on 7 months.
For me... I had "nothing wrong" physically or chemically... Nothing that could be determined UNLESS I was pregnant. For me, my placenta rips away (placental abruption) from the uterine wall with the LEAST provocation. Even my son's... was in a constant state of ripping away. When he was born, it had ripped slightly and regrown so often it was over 20 pounds!!! (most are 3-5lbs). Held up in the midwife's (I had a midwife OB team through my office, it was the 'high-risk-mama-combo') hands it stretched well over 3' and possibly 4' wide (I sort of forget). To have my son I was on modified bedrest almost the entire pregnancy. I can't tell you how often I was in tears with well meaning idiots saying I wasn't doing what was right for my baby and THIS kind of exercise was GOOD for you. Thwibbt. No. Thank. You. Since even walking a block could cause a placental abruption in my case. Much less something STUPID like yoga (I live in a very yoga-area. I LIKE yoga. But no exercise could be worse designed for someone with my condition. Even leaning to *reach toilet paper* could cause a twinge and spotting. Much less real, honest to god, prenatal yoga. Yoga was instant-miscarriage for me. Not that strangers would believe me. Seriously. I had to have been majorly hormonal to be explaining myself to STRANGERS! lol. Stupid hormones!).
If there IS something wrong... you're going to get a lot of hurtful advice from well meaning idiots that you will need to ignore.
Which is my little Bluebird of Happiness moment. Feel free to thwack me upside the head. But seriously... our cases are ALL different. One kind of nutrition is GREAT for one person, and will trigger a miscarriage in another. Ditto exercise or no exercise. Supplements or no supplements. It reeeeeally all depends.
To ME (and I could be totally wrong) since you have no problem GETTING pregnant... I would think you don't need a fertility specialist (although you and hubby probably need bloodwork to ascertain if there is a lethal gene combo at play, rare, or an incompatibility). This (so far) sounds like 'regular OB' stuff to start with. An OB who specializes in high risk cases, but those are normal copays! From experience! A blood draw. A vaginal exam. A urine sample. An ultrasound. IF something is off physically (hormones, chemically in another way, physically) then a different specialist may well be needed. But there are soooo many possibilities don't jump to 20k IVF numbers floating in your mind to start. A LOT of problems can be fixed with a shot or taking a daily pill. Others can be fixed with some time, change of diet, change of exercise, circlage, etc.
Lots and lots of us high risk mama's pay EXACTLY what low risk mamas pay.
I don't know if you'll decide there is a point for you two. My point in inside doing his math homework and woke up this morning and gave me a flying hug and a "Good morning Mom! Love you!". Which isn't so common any more at 9 years old as it used to be. The pain of loss was worth it to wait for HIM.
