Is it going to be more difficult to get pregnant in the early 30's compare to early 20's? Last couple of months me and my husband were just talking about starting a family soon. Twice we BD-ed on near ovulation day and on ovulation day. Which falls on February and last month(July). My next period is in 4 days. I noticed that the two times we BD-ed near ovu and on O.D(which is in July) my allergic rhinitis flares up like crazy. Took some antihistamine it won't help.
