Christine • Rainbow baby boy born January 2017 🌈 after a missed miscarriage Dec`14, molar pregnancy Apr`15 and blighted ovum Feb'16
Hi! i just got my bfp yesterday! Today i got my blood test done (positive!) and tomorrow i'm seeing my dr. This is my first pregnancy ever and i'm very excited and scared, lol!  I imagine this has been asked a lot, but i was wondering, when did you start to show? I'm 5'-7", 138 pounds. I want to wait a few weeks before letting anyone else know (besides the daddy) and I'm worried i won't be able to hide it very long.
