What a roller coaster we've been on and I'm only 7 wks pregnant. My paragard IUD somehow failed dramatically and I'm now,tentatively, expecting twins. After confirming the pregnancy (and IUD location) with u/s, My midwife sent me to a high-risk OB clinic to have the IUD pulled. There it was discovered I had two embryos. whoa. So out came the paragard as easy as can be (thank goodness, the OB thought he could be in there for up to 15 minutes using his 'special tool', eeeegads). I haven't had any spotting, nothing. From that first scan at 5 wks, one embryo was much smaller than the other. The OB was extremely neutral about my chances of continuing on with a twin pregnancy...I'm not sure if he was trying to soothe our shock or just being very honest. So they had me come back today at 7wks for a viability check. The embryos have certainly gotten bigger but even to my very untrained eye things don't seem right. The u/s tech had to really hunt for a yolk sak/fetal pole in the larger embryo and there didn't seem to be anything yet in the 2nd. But it had what, tripled? in size from two weeks ago. Since discovering the surprise pregnancy was twins, my husband and I have become really quite excited about the possibility of having twins. We have one other child and had always planned on having a total of three. We'd both be heartbroken if we lost one embryo now. I go back next week for another scan.
What are your experiences with early twin detection and embryo sizes? Could the residual effects of the copper IUD cause development delays? I was actually charting for the first time in my life the month we conceived...I was planning on practicing for several months before we removed the IUD and tried to have #2. So I know when my ovulation temp spiked in comparison to when we had sex, when I had implantation spotting and cramping, etc. I am very certain of my dates. So I am concerned about the lack of growth and what this could mean for both embryos. On one hand, I'm happy to see the smaller embryo getting bigger. On the other, at 7 wks shouldn't there be a heartbeat?
Sorry this is so rambly and unorganized. I'm a big giant jumble of emotions right now. Thank you for reading this and any thoughts you might have.
