Hi all, I am new here. I have 3 little girls and would welcome another little one I am on CD4 of AF.. Since I started, I have had nausea, backache, cramping, tiredness, tingling sensation in my breasts and today I tried an OPK just to see what it said and I had to lines. WTH?? We BD on 3/31 and 4/6 I ovulated around the 2nd of April. Could I be pregnant? My period is normal as far as the flow. But the symptoms are throwing me off, I never have had nausea or sore breasts before or during my periods. Any ideas? Oh and a hpT is bfn.
