Hi Have irregular cycles, poly cystic..period was due on 9th. Did not get period, we are ttc, as there is a pooja at home on 20th doc prescribed susten 200. Did hpt twice, once on 10 and other on 13. Both negative. I now sometimes feel like vomiting and jus puke dont actually vomit. Could i be pregnant. Should i do a test while on this medication?
