Suggest Treatment For Vaginal Pain During Intercourse While On Losetrin

I have been taking lo losetrin fe 28 for about seven months now after I was on Heather pill for about ten months since I was nursing my first child. Condoms have always broke when used. Newer methods scare me ex, IUDs and patches, so the pills my method of choice. Since I was 15 I have religiously taken the pill (many dif types) and never had any real side effects or anything. My husband and I are both faithful and I am wanting to try to get pregnant again soon so a change right now isn't real feasible. I also have to stay on lo losetrin fe bc I have had HBP. To my question: I have realized that every time my husband and I have intercourse there's pain during which is eased with lube but not completely gone, after sex the next few days feel like I have a yeast infection. I have had several in my lifetime but never so frequent. If we don't have sex again the symptoms usually go away by day three or four, but if I use the creams they go away pretty quick a day or two. But as soon as we have sex again it's back. I did some research and I see a lot of women on lo losetrin complain of these side effects.. Is there anything I can do or should do or can do? Options advice please.
