HI Sakshi-
I totally understand you being worried right now…BUT you really can not get an accurate pregnancy test until 5 days AFTER your missed period. I know it can be hard to wait and takes a lot of patience, but that is all you can really do right now.
If you end up missing your period, you can go to this website http://www.optionline.org and enter your city name and a list of Pregnancy Centers in your area will come up. You can go there and get a FREE and CONFIDENTIAL pregnancy test done. They are awesome at the centers and can help you with all of the questions you may be having.
I hope this helps a bit. Hang in there!
Luv- Molly
