My lmp was the 23rd December ( due date 29 sept) and I ovulated on the 5th January so concieved a few days either side of that date.
If you had concieved December 12-20 you wouldn't have got your period the end of December.
You should bring up your concerns with your doctor though. they will be able to tell you the halflife of the drug you were taking ( how long it stays in your system) and what the probability of it causing any effects on the baby would be.
But try to relax you didn't take it while pregnant at so I'm guessing the risk would be low if any and it's an unpreventable risk you can't change the fact you needed meds so really nothing to beat yourself up over
Thank you!! And congrats to you
We conceived via artificial insemination on Dec. 21 and I am due Sept. 13 (17 weeks 4 days today). You should be in the clear, depending on how long that med stayed in your system.
