Problems Trying to conceive. Conceive?

I was experiencing low bleeding (brownish blood) during 1 to 5th day of my period then heavy flow on 6th nd 7th day. Is this normal? I had an abortion done in april 2015, then I got married to the same person who I had my first pregnancy with. since then my cycles have changed. I get my period on time every month its just my bleeding patterns have changed.I am trying to conceive since January 2017 I consulted doctors , they all told me its hormonal imbalance. Its just I wanted this problem to get diagnosed as my bleeding is about 10 day long(light bleeding throughout ,heavy bleeding 2 days thats 6th and 7th day).Now I skipped a month (Last period date- 30/01/17) I have LO 2.1 cyst ET 1.3 My doctor gave me primolut N for 7 days.doctor asked me to undergo FSH,LH,prolactin,T3,T4,TSH tests.Will the medication primolut n affect my tests? Will I be able to conceive?
