I am 26 year old female and recently got married in November 2016, me and my partner both are virgin and we are facing issues with intercourse as whenever he try to put his penis in me, he only able to put in 30% and then I got dry and it pains me a lot?we have tried 3-4 times with and without condom but every time I got dry and he loses his erection also very quickly. Moreover, I am diagnosed with PCOD 6 month back, I have no other medical problem, now in November due to my marriage with the consultation from doctor, to get my periods date prepend, she gave me Meprate pills for 5 days twice a day, but due to these pills my date got delayed more and I got my periods even after my normal date in November. Now in December, my date was 17th and still I did not get my periods though I am having severe periods pain, nausea, legs pain and white discharge and it got delayed 10 days?. Now I am really worried as is it due to those pills which disturbed my cycle so badly? Or it might happen that I got pregnant? But I feel like I am still virgin as my partner just inserted 30% of his penis into me ?.So should I need any lubricant for this?
