I'm new to this site and currently trying to conceive. I am using conceive plus and have some first response ovulation tests.. I used to have Paraguard and ever since I got it taken out in November my periods have been 3 days and very light. this last month it came a whole 5 days early which isn't normal.. I'm not pregnant. anyways every time I take the ovulation tests the first line for the lh surge is light but you can see it.. does that mean that the lh surge is coming? it's been like that for 3 days now. sorry for the long post but my husband and I are desperately trying.
