Question???

AF is scheduled to come in about 6or 7 days. I have been experiencing a weird fluttering or almost like a vibration in my lower stomach area not a constant thing but here and there for the past couple days.. Tender breasts but mine tend to get that way before Af .. I don't want to take a test yet because I know it is still a little early and to be completely honest I don't want another disappointment. I feel like I hve these symptoms but I almost don't want to believe them because I don't want that false test to come up! I try and stay realistically positive about this and my hubby and I only had sex once durning ovulation it was glows most fertile day for me but we just have decided to kinda take it easy until after summer with us both working a lot of hours right now .. So I don't know. Any other ladies ever have this fluttering feeling??
