Hi there, I have understood your concern. I will suggest you the best possible treatment options. 
1 ) First of all do not panic. 
2 ) As you have unusual bleeding pattern in the cycle and you are also planning to get pregnant,  you need to confirm 
pregnancy.  In case of positive pregnancy test, your symptoms can be related to pregnancy. 
3 ) To clear the dilemma about pregnancy, I will suggest you to get morning's first sample of urine tested for pregnancy. In case of doubt blood 
beta HCG test and USG will be of help. 
4 )  If your pregnancy test is positive, then please contact your treating gynecologist. Please seek prescription support for oral micronized 
progesterone tablets, anti emetics like 
Doxylamine and 
Pyridoxine combination. 
USG will be of help to know about the 
gestational age and viability of pregnancy. 
5 ) If pregnancy test is negative, then you need not worry. But start on 
Folic acid, Vitamin B 12 and Omega 3 supplements on daily basis  at least 3 months before you plan to get pregnant. This helps to prevent many problems during pregnancy and delivery.  
I hope this answer helps you. 
Thanks.
